I don't really understand why you could see that (didn't find the
line that produces this output), but I'm glad it worked for you. :)

That's the same number as ncurses' keypad() token for Enter; from
ncurses.h:

  #define KEY_ENTER       0527            /* Enter or send (unreliable) */

I don't know why that's seen in MacLynx, since I have no idea how it's
compiled, but it appears to use a curses library similar enough to
ncurses (and have keypad() enabled).

Newer versions of lynx - since 1998-11-23 (2.8.2dev.7), see CHANGES -
should already map this to '\n' (if compiled with a (n)curses.h that
has that definition).

You can use that code - obviously you want to, if you have no better
way - but don't be surprised if it stops working in a future version,
or in a lynx compiled differently.

CTRL-C is obviously different from ENTER, despite the fact that some Mac
tools happen to show the same code...

I think your lynx sees CTRL-C as 0x03, so a KEYMAP:0x03 should affect
it.  (But on UNIX, lynx normally doesn't "see" CTRL-C as a character
at all - it sees an interrupt instead, so the KEYMAP:0x03 would have
no effect.  Unless CTRL-C does not generate an interrupt, which can
be achieved with the stty command.)
