Note: setting emacs/vi keys ON has no direct effect on line-editor bindings.
This is the Bash-like Binding keymap.
ENTER Input complete - Enter, RETURN TAB Completion / Next - TAB, Do ABORT Cancel / Undo Change - C-g, C-_ ERASE Erase the line - M-k, C-x k BACK Cursor back char - Left-Arrow, C-b FORW Cursor forward char - Right-Arrow, C-f BACKW Cursor back word - M-b, C-r FORWW Cursor forward word - M-f, C-s  BOL Go to begin of line - C-a, Home, Find EOL Go to end of line - C-e , End, Select DELP Delete prev char - C-h, Backspace, Rubout DELN Delete next  char - C-d, Delete, Remove DELPW Delete prev word - C-w , M-Backspace, M-Delete (?) DELNW Delete next word - M-d DELBL Delete to beg of line - C-u DELEL Delete to end of line - C-k  UPPER Upper case the line - M-u LOWER Lower case the line - M-l LKCMD Invoke cmd prompt - C-v [FORM] SWMAP Switch input keymap - C-^ (if compiled in) Special commands for use in textarea fields [FORM]: PASS! Textarea external edit - C-e C-e , C-x e PASS! Insert file in textarea - C-x i PASS! Grow textarea - C-x gHere is a little textarea for practice:
Advanced emacs-like commands: TPOS Transpose characters - C-t SETMARK Set mark at current position in line - C-@ XPMARK Exchange current position with mark - C-x C-x KILLREG Kill region between mark and position - C-x C-w  YANK Insert text last killed (with KILLREG) - C-y
C-key means Control+key.
C-x key means first Control+x, then key. M-key means Meta+key, where Meta is a modifier that can be entered in a variety of ways:
 "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.  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.  C-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.  These keys invoke special behavior when pressed twice in a row: C-e C-e calls the external editor for changing the text in a textarea (if available). C-k C-k will move to the next link, so that all lines in a textarea can be conveniently cleared by repeating C-k.  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 doesn't apply. [FORM] In form text fields, only. Ignored by Line Editor elsewhere. More notes 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 C-x or Meta currently have no effect (see the Key Map Page accessible with the key K for current information).

[emacskey] Normal key action subject to emacs_keys setting. [!] Action of key with Meta modifier follows action of key without Meta. If you manage to enter the Meta key while Line-Editor Binding is not set to Bash-Like, and the unmodified binding is different from that listed here, M-<key> will act like <key>.
