Loadkeys trickery

Loadkeys trickery

Hello!

I work in linux terminal. I use fbterm and tmux.
I use loadkeys to get more keychords. Here is example of my config:

  keymaps 0-255
  alt keycode 1 = 0xFFFF
  control keycode 105 = 0xFFFE
  control keycode 106 = 0xFFFD
  control keycode 103 = 0xFFFC
  control keycode 108 = 0xFFFB
  ctrll keycode 103 = 0xFFFA
  shift keycode 57 = 0xFFF9
  keycode 56 = Alt
  keycode 100 = AltGr
  keycode 125 = ShiftL
  keycode 127 = ShiftR
  keycode 29 = CtrlL
  keycode 97 = CtrlR
  keycode 58 = Control

These 0xFFFF are some tibetian symbols, their exact values does not
matter. Under linux console, I can happily press (Shift + Space(=keycode
57)) and get strange symbol, and bind it to some command in emacs.  If I
start tmux, and press (Shift + Space), I get same strange symbol into
bash prompt. It is great. But! If I start emacs under tmux and press
Shift+Space, emacs interprets it as F10 and open text menu. I checked,
Vim works as expected (prints tibetian symbol).

Usually I run fbterm and tmux in it. Fbterm breaks nothing, but adds 256
colors.

Interesting enough, if I set TERM=linux under tmux, things works well.
I could set it for emacs, but I am unwilling to give up 256 colors.

Also I tried screen over tmux. Same result.

Maybe someone have idea or encountered such problem? Thank in advance for your
attention.

 Hi,

 Sorry, I can not help you, but need your help :)
 How you got that key code map correctly? Different term have
different key code bind, how you known the number of each key exactly?

Thanks :)

If I understand you correctly, you need showkey(1).

PS. Please, do not overquote.

PPS. I somehow worked around my problem. I do not understand why,
but if I start emacs via dtach(1) and have (server-start) in init file,
it works correctly, but if I use emacs --daemon, it does not.

You can use ‘showkey’ to get the keycodes.
