Mapping unsupported keys with xmodmap

Here is the plan:

• bind the currently unassigned keycodes to unused keysyms (e.g. F13, F14, ...)
• use xbindkeys or khotkeys (KDE) to execute commands (scripts, DCOP, ...) when those keys are pressed
  

To find the keycodes of the unsupported keys, use the following command:

xev | grep -A2 --line-buffered '^KeyRelease' | sed -n '/keycode /s/^.*keycode \([0-9]*\).* (.*, \(.*\)).*$/\1 \2/p'

Use your favorite text editor (vim, emacs, kate, nano, whatever) and put the corresponding lines in a file named .Xmodmap (note the dot and the capital X) under your home directory, like this:

keycode 160 = F13
keycode 174 = F14
keycode 176 = F15
...
