/* ***** NOTES: *****
If you add definitions for new lynxkeycodes to the above list that
need to be mapped to LYK_* lynxactioncodes -
- AT LEAST the tables keymap[] and key_override[] in LYKeymap.c
have to be changed/reviewed, AS WELL AS the lineedit binding
tables in LYEditmap.c !
- KEYMAP_SIZE, defined in LYKeymap.h, may need to be changed !
- See also table named_keys[] in LYKeymap.c for 'pretty' strings
for the keys with codes >= 256 (to appear on the 'K'eymap page).
New keycodes should probably be assigned consecutively, so their
key names can be easily added to named_keys[] (but see next point).
They should also be documented in lynx.cfg.
- The DOS port uses its own native codes for some keys, unless
they are remapped by the code in LYgetch(). See *.key files
in docs/ directory. Adding new keys here may conflict with
those codes (affecting DOS users), unless/until remapping is
added or changed in LYgetch().
(N)curses keypad codes (KEY_* from curses.h) can also directly
appear as lynxkeycodes and conflict with our assignments, although
that shouldn't happen - the useful ones should be recognized in
LYgetch().
- The actual recognition of raw input keys or escape sequences, and
mapping to our lynxkeycodes, take place in LYgetch() and/or its
subsidiary functions and/or the curses/slang/etc. libraries.
The basic lynxkeycodes can appear combined with various flags in
higher-order bits as extended lynxkeycodes; see macros in LYKeymap.h.
The range of possible basic values is therefore limited, they have
to be less than LKC_ISLKC (even if KEYMAP_SIZE is increased).
