Make apps invisble in the desktop pager

>just as soon as I figure out where my meta key is.
Derek,
I did it in a dazed blur of KDE settings and cannot recall the exact steps.
Try this:
K -> System Settings -> Regional & Acc -> Keyboard Layout -> Xkb Options
Enable
Alt/Win key behaviour

Then:
RightClick on title bar -> Config Win Behav -> Actions -> Window Actions
Mess around in there.

I think the meta key is left ALT by default. It could be the Win key too. I 
set mine to Win as I use left ALT in inkscape and Blender etc.
