[wmii] How to bind the Pause key (or any other one) to execute a random non-wmii-specific program

[michael_der gulliUser]

Hi folks,

I've already searched the Internet, but with no success. This far I've only
found guides on how to change the Meta-Key or keybindings to wmii functions
(like Meta-p).
However, I would really like to execute a program just by the push of a
button and not by means of dmenu.So:
Is there a way to bind (for example) the Pause key to execute (for example)
iceweasel?
I've tried to add
=================================
Key Pause
       sh -c "iceweasel"
=================================
to the wmiirc. It did not work.

Any ideas?

Thanks in advance,

Michael
