[LINUX5250] Confused about keyboards

[Phillip.Watts@xxxxxxxxx]

For whatever reason my company wants to use 122 keyboards.
Use to dumb terminals I guess.

I have learned with the help of Scott and James (thanks) to map keys
in .Xdefaults.  Cool.
But that depends on the key having a name. Like Return or KP_enter or Control_R.

When I attach  a 122 keyboard and run  xev,  some of the keys produce nothing or
nonsense.  Like F13 produces  "Prior".
With the showkey utlity, I can find the scancode for all these keys.
F13 is 100.

WELL, the ONLY place in the Linux system I have been able to equate scancodes to
keynames is in   keymaps/us.kmap.gz.
That's cool I can modify that file so that right control (scan code 97) produces
"Return".
Then do loadkeys and it works for  the console.

But not in X.

Can anyone tell me where are the files which causes X to equate a scancode like
97
to the symbol "Control_R"  or 100 to "F13"?
Thanks
