<P><STRONG>
I would like to use the special keys on my Microsoft Natural Keyboard Pro
under Linux.
I have already found the keycodes (I think it was xevt), but I haven't been
able to define a program for a key, e.g. the standby button starts xlock,
the e-mail button starts kmail, volume + and - enables kmix and changes the
volume, and so on.
</STRONG></P>

When you have the keycode (xev) you can setup the keys using xmodmap. This
influences only keys in X -- not on conlsole.
Basically it will map the hardware keycode to a symbolic keysymbol -- xev is
showing the actual symbol along with the keycode.
</BLOCKQUOTE>
<BLOCKQUOTE>
For example I've set the "print" scroll" "pause" buttons to "front" back"
"iconify" functionality. (doesn't even need .Xmodmap since the keys already
produce keysymbols "print" "Scroll_Lock" and "pause").
</BLOCKQUOTE>
<BLOCKQUOTE>
If you want to use the Winkeys add something like to your .Xmodmap:
</BLOCKQUOTE>
<blockquote><pre>keycode 0x75 = Menu ! (is the menu key here)
</pre></blockquote>
<BLOCKQUOTE>
then run:
</BLOCKQUOTE>
<blockquote><pre>xmodmap .Xmodmap
</pre></blockquote>
<BLOCKQUOTE>
to read in the new settings.
</BLOCKQUOTE>
<BLOCKQUOTE>
But now the next problem: If your window manager does not know these
keysymbols and what to do on key press, nothing will happen. I use the fvwm2
windowmanager here and I can set it in .fvwm2rc by something like:
</BLOCKQUOTE>
<blockquote><pre>Key Print A N Raise
Key Scroll_Lock A N Lower
Key Pause A N Iconify
</pre></blockquote>
<BLOCKQUOTE>
for the front, back, iconify
</BLOCKQUOTE>
<blockquote><pre>Key Delete A CM Exec exec xlock -modelist "matrix"
</pre></blockquote>
<BLOCKQUOTE>
will start the screen saver on Ctrl-Alt-Del
</BLOCKQUOTE>
<BLOCKQUOTE>
If you use kde or whatever windowmanager you will have to figure out how to
define these key actions. The manual page of the windowmanager would be a good
starting point.
