[Novalug] F13-F24 keys?

[Ed James]

Brandon,

   I don't have the answer, but I'm poking around for it.  In the
meantime, I have an
FYI - use "xmodmap -pk" to see what your current keymap table is.  My table only
goes up to F12.  I found a file "/usr/include/X11/keysymdef.h" which
looks like a
clue towards getting additional PFKs to work.  However, that might just work for
keyboards that physically have extra PFKs.

   I'm playing with Xlib coding now, but can only generate XK_F1 to
XK-F12 signals
since that's all I have on my keyboard.  However, my XWindow server
does have know
the keycode for F13..., even though I can't generate them via a
keyboard yet (I am
able to generate it via and home-built XWindow app).

   "Shift-F1" generates 2 sequential keycodes which an XWindow app could "map"
to an F13 keysym, but that's a pain to do.  I dunno what the real way is yet.
