+ +

Overview

+ +

Lynx invokes a built-in Line Editor 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 Lynx was configured + with --disable-alt-bindings). If available, they may + be selected via the “o”ptions menu, or by editing + lineedit_mode in the “.lynxrc” file.

+ +

You can always see the current set of key-bindings in + Lynx by opening the special URL LYNXEDITMAP:. This page is provided for those + not using Lynx.

+ +

Note: setting emacs/vi keys ON has + no direct effect on line-editor bindings.

+ +

Special keys

+ +

See the Lynx Line + Editor page for an explanation of terminology and + key-names.

+ +

Notes

+ +
    +
  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.
    2. + +
  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.
    3. + +
  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.
    4. + +
  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.
    5. + +
  5. Key is likely unavailable for + Lynx, 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.
    6. + +
  6. where [FORM] is marked, + indicates that the binding is effective only in form text + fields. It is ignored by Line Editor elsewhere.
    7. +
+ +

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 Key Map Page + accessible with the key K for current + information).

+ +

Additional + details
