The Linux console acts + like that by default for most keys; Kermit can be set up to do it, + xterm can be for some keys, and so on. But the same caveats as for + the previous item apply. + This Alt mapping may also be possible, independent of the ESC character, + for some keys in Lynx for DOS/i386 or for Win32. +<LI>C-x <strong><kbd>key</kbd></strong>. + Actually, currently the same internal table is used for Meta and the + C-x prefix. Therefore all M-<strong><kbd>key</kbd></strong> combinations can + also be typed as C-x <strong><kbd>key</kbd></strong>, and vice versa. +</UL><pre> +[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] 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] 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. +[4] 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. +[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 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 + <A HREF="LYNXKEYMAP:" + >Key Map Page</A> accessible with the key <kbd>K</kbd> for current information). + + +</pre> +<h2>Additional details on other keys, for the curious +(very much subject to change)</h2> +<pre> +Normal key action when used in form fields, subject to remapping +with KEYMAP: [FORM (except Up-Arrow, Down-Arrow)] + C-l [3], C-o, C-z [5], C-\ [5], C-] [5] + C-n [emacskey], C-p [emacskey] + Up-Arrow [2], Down-Arrow [2] + Page-Up, Page-Down, F1, Back-Tab + +Normal key command with Meta modifier ignored when used in form fields, +subject to remapping with KEYMAP: [FORM (except Up-Arrow, Down-Arrow)] + M-C-l [3], M-C-o [!], M-C-z [5], M-C-\ [5], M-C-] [5] + M-C-u, M-/, M-n + M-Up-Arrow [2][!], M-Down-Arrow [2][!] + M-Page-Up [!], M-Page-Down [!], M-Home, M-End + +Passed as specific command: + lynx action duplicates by default + ----------- --------------------- + M-C-d NEXT_LINK Down-Arrow + M-C-e EDITTEXTAREA C-e C-e + M-C-k LPOS_NEXT_LINK (none, Down-Arrow suggested) + M-e EDITTEXTAREA C-e C-e + M-g GROWTEXTAREA (none, C-v $ suggested?) + M-i INSERTFILE (none, C-v # suggested?) + M-< HOME M-Home + M-> END M-End + M-F1 DWIMHELP F1 + M-Find WHEREIS C-v / + M-Select NEXT C-v n + +Duplicates function of other key(s): + edit action duplicates + ----------- ---------- + M-C-b BACKW M-b, C-r + M-C-f FORWW M-f + M-C-n FORWW M-f + M-C-p BACKW M-b, C-r + M-C-r BACKW M-b, C-r + M-a BOL C-a, Home, ... + +Modifier ignored, and duplicates function of other key(s): + edit action duplicates + ----------- ---------- + M-C-a BOL C-a, Home, ... + M-C-g ABORT C-g, ... + M-TAB TAB C-i [!] + M-C-j ENTER C-m, C-j, Enter / RETURN + M-RETURN ENTER C-m, C-j, Enter / RETURN + M-C-y YANK C-y [!] + M-C-^ SWMAP C-^ [!] (if compiled in) + M-Right-Arrow FORW Right-Arrow [!], C-f + M-Left-Arrow BACK Left-Arrow [!], C-b + M-Do TAB C-i [!] + +Key completely ignored: + C-q, Insert + M-C-q, M-C-s [5], M-C-t, M-C-v, M-ESC + M-C-@, M-C-_, M-Remove, M-Insert [!] + +Meta + other (mostly, printable character) keys: + Modifier ignored, or sequence swallowed (see [5]). + M-@, M-E...M-Z [5], M-\, M-^, M-_ attempt to interpret + as 7-bit escape representation for character in 8-bit + control (C1) range if appropriate according to + Display Character Set. + + +[emacskey] Normal key action subject to emacs_keys setting. +[!] Action of key with Meta modifier follows action of key without + Meta.
