Introduction *windows-intro* *window* + +Summary: + A buffer is the in-memory text of a file. + A window is a viewport on a buffer. + A tab page is a collection of windows. + +A window is a viewport onto a buffer. You can use multiple windows on one +buffer, or several windows on different buffers. + +A buffer is a file loaded into memory for editing. The original file remains +unchanged until you write the buffer to the file. + +A buffer can be in one of three states: + + *active-buffer* +active: The buffer is displayed in a window. If there is a file for this + buffer, it has been read into the buffer. The buffer may have been + modified since then and thus be different from the file. + *hidden-buffer* +hidden: The buffer is not displayed. If there is a file for this buffer, it + has been read into the buffer. Otherwise it's the same as an active + buffer, you just can't see it. + *inactive-buffer* +inactive: The buffer is not displayed and does not contain anything. Options + for the buffer are remembered if the file was once loaded. It can + contain marks from the |viminfo| file. But the buffer doesn't + contain text. + +In a table: + +state displayed loaded ":buffers" ~ + in window shows ~ +active yes yes 'a' +hidden no yes 'h' +inactive no no ' ' + +Note: All CTRL-W commands can also be executed with |:wincmd|, for those +places where a Normal mode command can't be used or is inconvenient. + +The main Vim window can hold several split windows. There are also tab pages +|tab-page|, each of which can hold multiple windows. + *window-ID* *winid* *windowid* +Each window has a unique identifier called the window ID. This identifier +will not change within a Vim session. The |win_getid()| and |win_id2tabwin()| +functions can be used to convert between the window/tab number and the +identifier. There is also the window number, which may change whenever +windows are opened or closed, see |winnr()|. +The window number is only valid in one specific tab. The window ID is valid +across tabs. For most functions that take a window ID or a window number, the +window number only applies to the current tab, while the window ID can refer +to a window in any tab. + +Each buffer has a unique number and the number will not change within a Vim +session. The |bufnr()| and |bufname()| functions can be used to convert +between a buffer name and the buffer number. + +============================================================================== +2. Starting Vim *windows-starting* + +By default, Vim starts with one window, just like Vi. + +The "-o" and "-O" arguments to Vim can be used to open a window for each file +in the argument list. The "-o" argument will split the windows horizontally; +the "-O" argument will split the windows vertically. If both "-o" and "-O" +are given, the last one encountered will be used to determine the split +orientation. For example, this will open three windows, split horizontally: > + vim -o file1 file2 file3 + +"-oN", where N is a decimal number, opens N windows split horizontally. If +there are more file names than windows, only N windows are opened and some +files do not get a window. If there are more windows than file names, the +last few windows will be editing empty buffers. Similarly, "-ON" opens N +windows split vertically, with the same restrictions. + +If there are many file names, the windows will become very small. You might +want to set the 'winheight' and/or 'winwidth' options to create a workable +situation. + +Buf/Win Enter/Leave |autocommand|s are not executed when opening the new +windows and reading the files, that's only done when they are really entered. + + *status-line* +A status line will be used to separate windows. The 'laststatus' option tells +when the last window also has a status line: + 'laststatus' = 0 never a status line + 'laststatus' = 1 status line if there is more than one window + 'laststatus' = 2 always a status line + +You can change the contents of the status line with the 'statusline' option. +This option can be local to the window, so that you can have a different +status line in each window. + +Normally, inversion is used to display the status line. This can be changed +with the 's' character in the 'highlight' option. For example, "sb" sets it to +bold characters. If no highlighting is used for the status line ("sn"), the +'^' character is used for the current window, and '=' for other windows. If +the mouse is supported and enabled with the 'mouse' option, a status line can +be dragged to resize windows. + +Note: If you expect your status line to be in reverse video and it isn't, +check if the 'highlight' option contains "si". In version 3.0, this meant to +invert the status line. Now it should be "sr", reverse the status line, as +"si" now stands for italic! If italic is not available on your terminal, the +status line is inverted anyway; you will only see this problem on terminals +that have termcap codes for italics. + + *filler-lines* +The lines after the last buffer line in a window are called filler lines. By +default, these lines start with a tilde (~) character. The 'eob' item in the +'fillchars' option can be used to change this character. By default, these +characters are highlighted as NonText (|hl-NonText|). The EndOfBuffer +highlight group (|hl-EndOfBuffer|) can be used to change the highlighting of +the filler characters. + +============================================================================== +3. Opening and closing a window *opening-window* + +CTRL-W s *CTRL-W_s* +CTRL-W S *CTRL-W_S* +CTRL-W CTRL-S *CTRL-W_CTRL-S* +:[N]sp[lit] [++opt] [+cmd] [file] *:sp* *:split* + Split current window in two. The result is two viewports on + the same file. + + Make the new window N high (default is to use half the height + of the current window). Reduces the current window height to + create room (and others, if the 'equalalways' option is set, + 'eadirection' isn't "hor", and one of them is higher than the + current or the new window). + + If [file] is given it will be edited in the new window. If it + is not loaded in any buffer, it will be read. Else the new + window will use the already loaded buffer. + + Note: CTRL-S does not work on all terminals and might block + further input, use CTRL-Q to get going again. + Also see |++opt| and |+cmd|. + *E242* *E1159* + Be careful when splitting a window in an autocommand, it may + mess up the window layout if this happens while making other + window layout changes. + +CTRL-W CTRL-V *CTRL-W_CTRL-V* +CTRL-W v *CTRL-W_v* +:[N]vs[plit] [++opt] [+cmd] [file] *:vs* *:vsplit* + Like |:split|, but split vertically. The windows will be + spread out horizontally if + 1. a width was not specified, + 2. 'equalalways' is set, + 3. 'eadirection' isn't "ver", and + 4. one of the other windows is wider than the current or new + window. + If N was given make the new window N columns wide, if + possible. + Note: In other places CTRL-Q does the same as CTRL-V, but here + it doesn't! + +CTRL-W n *CTRL-W_n* +CTRL-W CTRL_N *CTRL-W_CTRL-N* +:[N]new [++opt] [+cmd] *:new* + Create a new window and start editing an empty file in it. + Make new window N high (default is to use half the existing + height). Reduces the current window height to create room (and + others, if the 'equalalways' option is set and 'eadirection' + isn't "hor"). + Also see |++opt| and |+cmd|. + If 'fileformats' is not empty, the first format given will be + used for the new buffer. If 'fileformats' is empty, the + 'fileformat' of the current buffer is used. This can be + overridden with the |++opt| argument. + Autocommands are executed in this order: + 1. WinLeave for the current window + 2. WinEnter for the new window + 3. BufLeave for the current buffer + 4. BufEnter for the new buffer + This behaves like a ":split" first, and then an ":enew" + command. + +:[N]new [++opt] [+cmd] {file} +:[N]sp[lit] [++opt] [+cmd] {file} *:split_f* + Create a new window and start editing file {file} in it. This + behaves almost like a ":split" first, and then an ":edit" + command, but the alternate file name in the original window is + set to {file}. + If [+cmd] is given, execute the command when the file has been + loaded |+cmd|. + Also see |++opt|. + Make new window N high (default is to use half the existing + height). Reduces the current window height to create room + (and others, if the 'equalalways' option is set). + +:[N]vne[w] [++opt] [+cmd] [file] *:vne* *:vnew* + Like |:new|, but split vertically. If 'equalalways' is set + and 'eadirection' isn't "ver" the windows will be spread out + horizontally, unless a width was specified. + +:[N]sv[iew] [++opt] [+cmd] [file] *:sv* *:sview* *splitview* + Same as ":split", but set 'readonly' option for this buffer. + +:[N]sf[ind] [++opt] [+cmd] {file} *:sf* *:sfi* *:sfind* *splitfind* + Same as ":split", but search for {file} in 'path' like in + |:find|. Doesn't split if {file} is not found. + +CTRL-W CTRL-^ *CTRL-W_CTRL-^* *CTRL-W_^* +CTRL-W ^ Split the current window in two and edit the alternate file. + When a count N is given, split the current window and edit + buffer N. Similar to ":sp #" and ":sp #N", but it allows the + other buffer to be unnamed. This command matches the behavior + of |CTRL-^|, except that it splits a window first. + + *CTRL-W_:* +CTRL-W : Does the same as typing |:| - enter a command line. Useful in a + terminal window, where all Vim commands must be preceded with + CTRL-W or 'termwinkey'. + +Note that the 'splitbelow' and 'splitright' options influence where a new +window will appear. + *E36* +Creating a window will fail if there is not enough room. Every window needs +at least one screen line and column, sometimes more. Options 'winminheight' +and 'winminwidth' are relevant. + + *:vert* *:vertical* +:vert[ical] {cmd} + Execute {cmd}. If it contains a command that splits a window, + it will be split vertically. For `vertical wincmd =` windows + will be equalized only vertically. + Doesn't work for |:execute| and |:normal|. + + *:hor* *:horizontal* +:hor[izontal] {cmd} + Execute {cmd}. Currently only makes a difference for + `horizontal wincmd =`, which will equalize windows only + horizontally. + +:lefta[bove] {cmd} *:lefta* *:leftabove* +:abo[veleft] {cmd} *:abo* *:aboveleft* + Execute {cmd}. If it contains a command that splits a window, + it will be opened left (vertical split) or above (horizontal + split) the current window. Overrules 'splitbelow' and + 'splitright'. + Doesn't work for |:execute| and |:normal|. + +:rightb[elow] {cmd} *:rightb* *:rightbelow* +:bel[owright] {cmd} *:bel* *:belowright* + Execute {cmd}. If it contains a command that splits a window, + it will be opened right (vertical split) or below (horizontal + split) the current window. Overrules 'splitbelow' and + 'splitright'. + Doesn't work for |:execute| and |:normal|. + + *:topleft* *E442* +:to[pleft] {cmd} + Execute {cmd}. If it contains a command that splits a window, + it will appear at the top and occupy the full width of the Vim + window. When the split is vertical the window appears at the + far left and occupies the full height of the Vim window. + Doesn't work for |:execute| and |:normal|. + + *:bo* *:botright* +:bo[tright] {cmd} + Execute {cmd}. If it contains a command that splits a window, + it will appear at the bottom and occupy the full width of the + Vim window. When the split is vertical the window appears at + the far right and occupies the full height of the Vim window. + Doesn't work for |:execute| and |:normal|. + +These command modifiers can be combined to make a vertically split window +occupy the full height. Example: > + :vertical topleft split tags +Opens a vertically split, full-height window on the "tags" file at the far +left of the Vim window. + + +Closing a window +---------------- + +:q[uit] +:{count}q[uit] *:count_quit* +CTRL-W q *CTRL-W_q* +CTRL-W CTRL-Q *CTRL-W_CTRL-Q* + Without {count}: Quit the current window. If {count} is + given quit the {count} window. + *edit-window* + When quitting the last edit window (not counting help or + preview windows), exit Vim. + + When 'hidden' is set, and there is only one window for the + current buffer, it becomes hidden. When 'hidden' is not set, + and there is only one window for the current buffer, and the + buffer was changed, the command fails. + + (Note: CTRL-Q does not work on all terminals). + + If [count] is greater than the last window number the last + window will be closed: > + :1quit " quit the first window + :$quit " quit the last window + :9quit " quit the last window + " if there are fewer than 9 windows opened + :-quit " quit the previous window + :+quit " quit the next window + :+2quit " quit the second next window +< + When closing a help window, and this is not the only window, + Vim will try to restore the previous window layout, see + |:helpclose|. + +:q[uit]! +:{count}q[uit]! + Without {count}: Quit the current window. If {count} is + given quit the {count} window. + + If this was the last window for a buffer, any changes to that + buffer are lost. When quitting the last window (not counting + help windows), exit Vim. The contents of the buffer are lost, + even when 'hidden' is set. + +:clo[se][!] +:{count}clo[se][!] +CTRL-W c *CTRL-W_c* *:clo* *:close* + Without {count}: Close the current window. If {count} is + given close the {count} window. + + When the 'hidden' option is set, or when the buffer was + changed and the [!] is used, the buffer becomes hidden (unless + there is another window editing it). + + When there is only one |edit-window| in the current tab page + and there is another tab page, this closes the current tab + page. |tab-page|. + + This command fails when: *E444* + - There is only one window on the screen. + - When 'hidden' is not set, [!] is not used, the buffer has + changes, and there is no other window on this buffer. + Changes to the buffer are not written and won't get lost, so + this is a "safe" command. + +CTRL-W CTRL-C *CTRL-W_CTRL-C* + You might have expected that CTRL-W CTRL-C closes the current + window, but that does not work, because the CTRL-C cancels the + command. + + *:hide* +:hid[e] +:{count}hid[e] + Without {count}: Quit the current window, unless it is the + last window on the screen. + If {count} is given quit the {count} window. + + The buffer becomes hidden (unless there is another window + editing it or 'bufhidden' is "unload", "delete" or "wipe"). + If the window is the last one in the current tab page the tab + page is closed. |tab-page| + + The value of 'hidden' is irrelevant for this command. Changes + to the buffer are not written and won't get lost, so this is a + "safe" command. + +:hid[e] {cmd} Execute {cmd} with 'hidden' is set. The previous value of + 'hidden' is restored after {cmd} has been executed. + Example: > + :hide edit Makefile +< This will edit "Makefile", and hide the current buffer if it + has any changes. + +:on[ly][!] +:{count}on[ly][!] +CTRL-W o *CTRL-W_o* *E445* +CTRL-W CTRL-O *CTRL-W_CTRL-O* *:on* *:only* + Make the current window the only one on the screen. All other + windows are closed. For {count} see the `:quit` command + above |:count_quit|. + + When the 'hidden' option is set, all buffers in closed windows + become hidden. + + When 'hidden' is not set, and the 'autowrite' option is set, + modified buffers are written. Otherwise, windows that have + buffers that are modified are not removed, unless the [!] is + given, then they become hidden. But modified buffers are + never abandoned, so changes cannot get lost. + +============================================================================== +4. Moving cursor to other windows *window-move-cursor* + +CTRL-W <Down> *CTRL-W_<Down>* +CTRL-W CTRL-J *CTRL-W_CTRL-J* *CTRL-W_j* +CTRL-W j Move cursor to Nth window below current one.

Uses the + cursor position to select between alternatives. + +CTRL-W <Right> *CTRL-W_<Right>* +CTRL-W CTRL-L *CTRL-W_CTRL-L* *CTRL-W_l* +CTRL-W l Move cursor to Nth window right of current one. Uses the + cursor position to select between alternatives. + +CTRL-W w *CTRL-W_w* *CTRL-W_CTRL-W* +CTRL-W CTRL-W Without count: move cursor to window below/right of the + current one. If there is no window below or right, go to + top-left window. + With count: go to Nth window (windows are numbered from + top-left to bottom-right). To obtain the window number see + |bufwinnr()| and |winnr()|. When N is larger than the number + of windows go to the last window. + + *CTRL-W_W* +CTRL-W W Without count: move cursor to window above/left of current + one. If there is no window above or left, go to bottom-right + window. With count: go to Nth window, like with CTRL-W w. + +CTRL-W t *CTRL-W_t* *CTRL-W_CTRL-T* +CTRL-W CTRL-T Move cursor to top-left window. + +CTRL-W b *CTRL-W_b* *CTRL-W_CTRL-B* +CTRL-W CTRL-B Move cursor to bottom-right window. + +CTRL-W p *CTRL-W_p* *CTRL-W_CTRL-P* +CTRL-W CTRL-P Go to previous (last accessed) window. + + *CTRL-W_P* *E441* +CTRL-W P Go to preview window. When there is no preview window this is + an error. + {not available when compiled without the |+quickfix| feature} + +If Visual mode is active and the new window is not for the same buffer, the +Visual mode is ended. If the window is on the same buffer, the cursor +position is set to keep the same Visual area selected. + + *:winc* *:wincmd* +These commands can also be executed with ":wincmd": + +:[count]winc[md] {arg} + Like executing CTRL-W [count] {arg}. Example: > + :wincmd j +< Moves to the window below the current one. + This command is useful when a Normal mode cannot be used (for + the |CursorHold| autocommand event). Or when a Normal mode + command is inconvenient. + The count can also be a window number. Example: > + :exe nr .. "wincmd w" +< This goes to window "nr". + +============================================================================== +5. Moving windows around *window-moving* + +CTRL-W r *CTRL-W_r* *CTRL-W_CTRL-R* *E443* +CTRL-W CTRL-R Rotate windows downwards/rightwards. The first window becomes + the second one, the second one becomes the third one, etc. + The last window becomes the first window. The cursor remains + in the same window. + This only works within the row or column of windows that the + current window is in. + + *CTRL-W_R* +CTRL-W R Rotate windows upwards/leftwards. The second window becomes + the first one, the third one becomes the second one, etc. The + first window becomes the last window. The cursor remains in + the same window. + This only works within the row or column of windows that the + current window is in. + +CTRL-W x *CTRL-W_x* *CTRL-W_CTRL-X* +CTRL-W CTRL-X Without count: Exchange current window with next one. If there + is no next window, exchange with previous window. + With count: Exchange current window with Nth window (first + window is 1). The cursor is put in the other window. + When vertical and horizontal window splits are mixed, the + exchange is only done in the row or column of windows that the + current window is in. + +The following commands can be used to change the window layout. For example, +when there are two vertically split windows, CTRL-W K will change that in +horizontally split windows. CTRL-W H does it the other way around. + + *CTRL-W_K* +CTRL-W K Move the current window to be at the very top, using the full + width of the screen. This works like closing the current + window and then creating another one with ":topleft split", + except that the current window contents is used for the new + window. + + *CTRL-W_J* +CTRL-W J Move the current window to be at the very bottom, using the + full width of the screen. This works like closing the current + window and then creating another one with ":botright split", + except that the current window contents is used for the new + window. + + *CTRL-W_H* +CTRL-W H Move the current window to be at the far left, using the + full height of the screen. This works like closing the + current window and then creating another one with + `:vert topleft split`, except that the current window contents + is used for the new window. + + *CTRL-W_L* +CTRL-W L Move the current window to be at the far right, using the full + height of the screen. This works like closing the + current window and then creating another one with + `:vert botright split`, except that the current window + contents is used for the new window. + + *CTRL-W_T* +CTRL-W T Move the current window to a new tab page. This fails if + there is only one window in the current tab page. + When a count is specified the new tab page will be opened + before the tab page with this index. Otherwise it comes after + the current tab page. + +============================================================================== +6. Window resizing *window-resize* + + *CTRL-W_=* +CTRL-W = Make all windows (almost) equally high and wide, but use + 'winheight' and 'winwidth' for the current window. + Windows with 'winfixheight' set keep their height and windows + with 'winfixwidth' set keep their width. + To equalize only vertically (make window equally high) use + `vertical wincmd =`. + To equalize only horizontally (make window equally wide) use + `horizontal wincmd =`. + +:res[ize] -N *:res* *:resize* *CTRL-W_-* +CTRL-W - Decrease current window height by N (default 1). + If used after |:vertical|: decrease width by N. + +:res[ize] +N *CTRL-W_+* +CTRL-W + Increase current window height by N (default 1). + If used after |:vertical|: increase width by N. + +:res[ize] [N] +CTRL-W CTRL-_ *CTRL-W_CTRL-_* *CTRL-W__* +CTRL-W _ Set current window height to N (default: highest possible). + +:{winnr}res[ize] [+-]N + Like `:resize` above, but apply the size to window {winnr} + instead of the current window. + +z{nr}<CR> Set current window height to {nr}. + + *CTRL-W_<* +CTRL-W < Decrease current window width by N (default 1). + + *CTRL-W_>* +CTRL-W > Increase current window width by N (default 1). + +:vert[ical] res[ize] [N] *:vertical-resize* *CTRL-W_bar* +CTRL-W | Set current window width to N (default: widest possible). + +You can also resize a window by dragging a status line up or down with the +mouse. Or by dragging a vertical separator line left or right. This only +works if the version of Vim that is being used supports the mouse and the +'mouse' option has been set to enable it. + +The option 'winheight' ('wh') is used to set the minimal window height of the +current window. This option is used each time another window becomes the +current window. If the option is '0', it is disabled. Set 'winheight' to a +very large value, e.g., '9999', to make the current window always fill all +available space. Set it to a reasonable value, e.g., '10', to make editing in +the current window comfortable. + +The equivalent 'winwidth' ('wiw') option is used to set the minimal width of +the current window. + +When the option 'equalalways' ('ea') is set, all the windows are automatically +made the same size after splitting or closing a window. If you don't set this +option, splitting a window will reduce the size of the current window and +leave the other windows the same. When closing a window, the extra lines are +given to the window above it. + +The 'eadirection' option limits the direction in which the 'equalalways' +option is applied. The default "both" resizes in both directions. When the +value is "ver" only the heights of windows are equalized. Use this when you +have manually resized a vertically split window and want to keep this width. +Likewise, "hor" causes only the widths of windows to be equalized. + +The option 'cmdheight' ('ch') is used to set the height of the command-line. +If you are annoyed by the |hit-enter| prompt for long messages, set this +option to 2 or 3. + +If there is only one window, resizing that window will also change the command +line height. If there are several windows, resizing the current window will +also change the height of the window below it (and sometimes the window above +it). + +The minimal height and width of a window is set with 'winminheight' and +'winminwidth'. These are hard values, a window will never become smaller. + + +WinScrolled and WinResized autocommands ~ + *win-scrolled-resized* +If you want to get notified of changes in window sizes, the |WinResized| +autocommand event can be used. +If you want to get notified of text in windows scrolling vertically or +horizontally, the |WinScrolled| autocommand event can be used. This will also +trigger in window size changes. +Exception: the events will not be triggered when the text scrolls for +'incsearch'. + *WinResized-event* +The |WinResized| event is triggered after updating the display, several +windows may have changed size then. A list of the IDs of windows that changed +since last time is provided in the v:event.windows variable, for example: + [1003, 1006] + *WinScrolled-event* +The |WinScrolled| event is triggered after |WinResized|, and also if a window +was scrolled. That can be vertically (the text at the top of the window +changed) or horizontally (when 'wrap' is off or when the first displayed part +of the first line changes). Note that |WinScrolled| will trigger many more +times than |WinResized|, it may slow down editing a bit. + +The information provided by |WinScrolled| is a dictionary for each window that +has changes, using the window ID as the key, and a total count of the changes +with the key "all". Example value for |v:event| (|Vim9| syntax): + { + all: {width: 0, height: 2, leftcol: 0, skipcol: 0, topline: 1, topfill: 0}, + 1003: {width: 0, height: -1, leftcol: 0, skipcol: 0, topline: 0, topfill: 0}, + 1006: {width: 0, height: 1, leftcol: 0, skipcol: 0, topline: 1, topfill: 0}, + } + +Note that the "all" entry has the absolute values of the individual windows +accumulated. + +If you need more information about what changed, or you want to "debounce" the +events (not handle every event to avoid doing too much work), you may want to +use the `winlayout()` and `getwininfo()` functions. + +|WinScrolled| and |WinResized| do not trigger when the first autocommand is +added, only after the first scroll or resize.

The preview window *preview-window* + +The preview window is a special window to show (preview) another file. It is +normally a small window used to show an include file or definition of a +function. +{not available when compiled without the |+quickfix| feature} + +There can be only one preview window (per tab page). It is created with one +of the commands below. The 'previewheight' option can be set to specify the +height of the preview window when it's opened. The 'previewwindow' option is +set in the preview window to be able to recognize it. The 'winfixheight' +option is set to have it keep the same height when opening/closing other +windows. + *preview-popup* +Alternatively, a popup window can be used by setting the 'previewpopup' +option. When set, it overrules the 'previewwindow' and 'previewheight' +settings. The option is a comma-separated list of values: + height maximum height of the popup + width maximum width of the popup + highlight highlight group of the popup (default is Pmenu) +Example: > + :set previewpopup=height:10,width:60 + +A few peculiarities: +- If the file is in a buffer already, it will be re-used. This will allow for + editing the file while it's visible in the popup window. +- No ATTENTION dialog will be used, since you can't edit the file in the popup + window. However, if you later open the same buffer in a normal window, you + may not notice it's edited elsewhere. And when then using ":edit" to + trigger the ATTENTION and responding "A" for Abort, the preview window will + become empty. + + *:pta* *:ptag* +:pta[g][!] [tagname] + Does ":tag[!] [tagname]" and shows the found tag in a + "Preview" window without changing the current buffer or cursor + position. If a "Preview" window already exists, it is re-used + (like a help window is). If a new one is opened, + 'previewheight' is used for the height of the window. See + also |:tag|. + See below for an example. |CursorHold-example| + Small difference from |:tag|: When [tagname] is equal to the + already displayed tag, the position in the matching tag list + is not reset.

Useful + example: > + :psearch popen +< Like with the |:ptag| command, you can use this to + automatically show information about the word under the + cursor. This is less clever than using |:ptag|, but you don't + need a tags file and it will also find matches in system + include files. Example: > + :au!

CursorHold *.[ch] ++nested exe "silent! ptag " .. expand("<cword>") + +This will cause a ":ptag" to be executed for the keyword under the cursor, +when the cursor hasn't moved for the time set with 'updatetime'.

Using hidden buffers *buffer-hidden* + +A hidden buffer is not displayed in a window, but is still loaded into memory. +This makes it possible to jump from file to file, without the need to read or +write the file every time you get another buffer in a window. + + *:buffer-!* +If the option 'hidden' ('hid') is set, abandoned buffers are kept for all +commands that start editing another file: ":edit", ":next", ":tag", etc. The +commands that move through the buffer list sometimes make the current buffer +hidden although the 'hidden' option is not set. This happens when a buffer is +modified, but is forced (with '!') to be removed from a window, and +'autowrite' is off or the buffer can't be written. + +You can make a hidden buffer not hidden by starting to edit it with any +command, or by deleting it with the ":bdelete" command. + +The 'hidden' is global, it is used for all buffers. The 'bufhidden' option +can be used to make an exception for a specific buffer. It can take these +values: + <empty> Use the value of 'hidden'. + hide Hide this buffer, also when 'hidden' is not set. + unload Don't hide but unload this buffer, also when 'hidden' + is set. + delete Delete the buffer. + + *hidden-quit* +When you try to quit Vim while there is a hidden, modified buffer, you will +get an error message and Vim will make that buffer the current buffer. You +can then decide to write this buffer (":wq") or quit without writing (":q!"). +Be careful: there may be more hidden, modified buffers! + +A buffer can also be unlisted.

'winheight' also limits the number + of windows opened ('winwidth' if |:vertical| was prepended). + Buf/Win Enter/Leave autocommands are not executed for the new + windows here, that's only done when they are really entered. + When the |:tab| modifier is used new windows are opened in a + new tab, up to 'tabpagemax'. + +Note: All the commands above that start editing another buffer, keep the +'readonly' flag as it was. This differs from the ":edit" command, which sets +the 'readonly' flag each time the file is read. + +============================================================================== +12. Special kinds of buffers *special-buffers* + +Instead of containing the text of a file, buffers can also be used for other +purposes. A few options can be set to change the behavior of a buffer: + 'bufhidden' what happens when the buffer is no longer displayed + in a window. + 'buftype' what kind of a buffer this is + 'swapfile' whether the buffer will have a swap file + 'buflisted' buffer shows up in the buffer list + +A few useful kinds of a buffer: + +quickfix Used to contain the error list or the location list. See + |:cwindow| and |:lwindow|. This command sets the 'buftype' + option to "quickfix". You are not supposed to change this! + 'swapfile' is off. + +help Contains a help file. Will only be created with the |:help| + command. The flag that indicates a help buffer is internal + and can't be changed. The 'buflisted' option will be reset + for a help buffer. + +terminal A terminal window buffer, see |terminal|. The contents cannot + be read or changed until the job ends. + +directory Displays directory contents. Can be used by a file explorer + plugin. The buffer is created with these settings: > + :setlocal buftype=nowrite + :setlocal bufhidden=delete + :setlocal noswapfile +< The buffer name is the name of the directory and is adjusted + when using the |:cd| command. + + *scratch-buffer* +scratch Contains text that can be discarded at any time. It is kept + when closing the window, it must be deleted explicitly. + Settings: > + :setlocal buftype=nofile + :setlocal bufhidden=hide + :setlocal noswapfile +< The buffer name can be used to identify the buffer, if you + give it a meaningful name. + + *unlisted-buffer* +unlisted The buffer is not in the buffer list. It is not used for + normal editing, but to show a help file, remember a file name + or marks. The ":bdelete" command will also set this option, + thus it doesn't completely delete the buffer.
