Well ask around how many people use such bindings for lynx, or feel a
need to use them.

If this were such a popular requirement, then I would expect lots of
people using .lynx-keymaps.  I can't see much indication of that on

Is lynx a program that "can grab them"?  It depends.  There is no
standard way to transmit something like Control-Left over a serial line
or a telnet connection.  

Anyway, I didn't say "useless".  If you can use the stuff, fine.  Core
functionality of lynx shouldn't depend on it, though.

Maybe you should talk to whoever maintains the terminfo standard (if
there is such a thing).  It seems you aren't complainign about a limit
in size, but rather that there aren't any definitions for many keys
you would like to use.

Anyway, that being the case, there is no way to specify Control-Left
in a terminfo file (afaik).  Which means everyone who wants to use
it with lynx (assuming it's possible at all to transmit something distinct
for Control-Enter from the keyboard to lynx) has to know the escape
sequence or similar and make their own tweaks in .lynx-keymaps.  How
many people do?

Btw. Alt+[most letters] works fine for me in Lynx's lineeditor, without
any need for .lynx-keymap tweaks.  (Alt sends ESC = Meta prefix),
