<h2><a name="overview" id="overview">Overview</a></h2>
<p><strong>Lynx</strong> invokes a built-in <a href=
"edit_help.html">Line Editor</a> for entering strings in response
to prompts, in forms, and for email messages if an external
editor has not been defined. Alternative key bindings are
normally available (unless <strong>Lynx</strong> was configured
with <code>--disable-alt-bindings</code>). If available, they may
be selected via the “o”ptions menu, or by editing
lineedit_mode in the “.lynxrc” file.</p>
<p>You can always see the current set of key-bindings in
<strong>Lynx</strong> by opening the special URL <a href=
"LYNXEDITMAP:">LYNXEDITMAP:</a>. This page is provided for those
not using Lynx.</p>
<p><strong><em>Note:</em></strong> setting emacs/vi keys ON has
no direct effect on line-editor bindings.</p>
<h2><a name="bash_bindings" id="bash_bindings">Bash-like
bindings</a></h2>
<p>This is the <em>Bash-like Binding</em> keymap.</p>
<pre>
ENTER Input complete - Enter, RETURN
TAB Completion / Next - TAB, Do (<em><a href=
"#note_2">see note 2</a></em>)
ABORT Cancel / Undo Change - Ctrl-g, Ctrl-_
ERASE Erase the line - M-k, Ctrl-x k
BACK Cursor back char - Left-Arrow, Ctrl-b
FORW Cursor forward char - Right-Arrow, Ctrl-f
BACKW Cursor back word - M-b, Ctrl-r
FORWW Cursor forward word - M-f, Ctrl-s (<em><a href=
"#note_5">see note 5</a></em>)
BOL Go to begin of line - Ctrl-a, Home, Find
EOL Go to end of line - Ctrl-e, End, Select (<em><a href="#note_4">see note 4</a></em>)
DELP Delete prev char - Backspace
DELN Delete next char - Ctrl-d, Delete, Remove (<em><a href="#note_1">see note 1</a></em>)
DELPW Delete prev word - Ctrl-w, M-Backspace, M-Delete (<em><a href="#note_3">see note 3</a></em>)
DELNW Delete next word - M-d
DELBL Delete to beg of line - Ctrl-u
DELEL Delete to end of line - Ctrl-k (<em><a href=
"#note_4">see note 4</a></em>)
UPPER Upper case the line - M-u
LOWER Lower case the line - M-l
LKCMD Invoke cmd prompt - Ctrl-v [FORM] (<em><a href=
"#note_6">see note 6</a></em>)
SWMAP Switch input keymap - Ctrl-^ (if compiled in)
<a name="TASpecial" id=
"TASpecial">Special commands for use in textarea fields</a> [FORM]:
PASS! Textarea external edit - Ctrl-e Ctrl-e, Ctrl-x e (<em><a href="#note_4">see note 4</a></em>)
PASS! Insert file in textarea - Ctrl-x i
PASS! Grow textarea - Ctrl-x g
</pre>
<h2><a name="examples" id="examples">Try it yourself</a></h2>
<p>Here is a little textarea for practice:</p>
<form action="">
<p>
<textarea name="practice" cols="40" rows=
"5">This text cannot be submitted. Normally lines like
these would be part of a form that is filled out and
then submitted. You can move around here and delete
or add text as you like, using the Line-Editor keys.
</textarea><input type="reset" value="[reset content]">
</p>
</form>
<h2><a name="emacs_bindings" id="emacs_bindings">Emacs-like
commands</a></h2>
<pre>
TPOS Transpose characters - Ctrl-t
SETMARK Set mark at current position in line - Ctrl-@
XPMARK Exchange current position with mark - Ctrl-x Ctrl-x
KILLREG Kill region between mark and position - Ctrl-x Ctrl-w (<em><a href="#note_3">see note 3</a></em>)
YANK Insert text last killed (with KILLREG) - Ctrl-y
</pre>
<h2><a name="special_keys" id="special_keys">Special keys</a></h2>
<p>See the <em><a href="edit_help.html#special_keys">Lynx Line
Editor</a></em> page for an explanation of terminology and
key-names.</p>
<h2><a name="notes" id="notes">Notes</a></h2>
<ol>
<li id="note_1">"next" means the character "under" a box or
underline style cursor; it means "to the immediate right of" an
I-beam (between characters) type cursor.</li>
<li id="note_2">For entering strings in response to prompts
(that is, when not editing form text fields), some keys have
different actions: TAB tries to complete input based on
previous response; Up-Arrow and Down-Arrow may offer previous
response and next response, respectively, from recall buffer
for some prompts.</li>
<li id="note_3">Ctrl-w can only be used for editing functions
if its default KEYMAP to REFRESH is changed. This can be done
in the lynx.cfg file, for example with the line
"KEYMAP:^W:DO_NOTHING". This also applies for other keys: as
long as the key's action is mapped to REFRESH, either with an
explicit KEYMAP in lynx.cfg or by default, the key's Line
Editor binding is disabled.</li>
<li id="note_4">These keys invoke special behavior when pressed
twice in a row: Ctrl-e Ctrl-e calls the external editor for
changing the text in a textarea (if available). Ctrl-k Ctrl-k
will move to the next link, so that all lines in a textarea can
be conveniently cleared by repeating Ctrl-k.</li>
<li id="note_5">Key is likely unavailable for
<strong>Lynx</strong>, because it is interpreted by operating
system, comm program, or curses library, or swallowed as part
of escape sequence recognition. Binding is provided for the
benefit of those where this does not apply.</li>
<li id="note_6">where <strong>[FORM]</strong> is marked,
indicates that the binding is effective only in form text
fields. It is ignored by Line Editor elsewhere.</li>
</ol>
<p>When a text input field, including a textarea line, is
selected, the Line Editor functions get a first grab at the keys
entered. If a key has no function defined in the Line Editor
binding, it can either be ignored, or passed on for normal key
command handling, where modifiers like Ctrl-x or Meta currently
have no effect (see the <a href="LYNXKEYMAP:">Key Map Page</a>
accessible with the key <kbd>K</kbd> for current
information).</p>
<h2><a name="miscellaneous" id="miscellaneous">Additional
details</a></h2>

curious (very much subject to change)</p>
