+/*  ***** 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).
