[ale] Lost keys...

[dcorbin at machturtle.com (David Corbin)]

Certain key combinations that used to work in my IDE (eclipse) no longer do.  
It appears to be something in the OS/X/window manager.  I'm running Gentoo 
with KDE.  I've looked through the Control Center and not found them assigned 
to anything.

The two I know about are: CTRL+SPACE and CTRL+SHIFT+UpArrow.

What's the best way to:
 1)verify that it's NOT eclipse, and 
 2) determine what has 'stolen them'. 

Thanks
David
