[kde-linux] how to bind mouse buttons

[Linh.H.Phan@jpl.nasa.gov]

Hi,

  I am transitioning from TWM to KDE and I was wondering
how I can translate my TWM key bindings to KDE; for example,
I am used to have the "iconify" action mapped to 
"Alt+Shift+MouseButton1" with this in my .twmrc:

Button1 = m|s : w         : f.iconify

How can I configure KDE (using SUSE Linux 9.2) to do the same?  
I tried to go 
"Control Center->Regional & Accessibility->Keyboard Shortcuts->
Resize Window->Custom"
and then pressing the "Alt+Shift" + MouseButton1, but the 
MouseButton1 will not get reigster in the "Primary Shortcut".

Please help.

Thank you,

Linh
