By default, when one holds down Alt and drags with the mouse, it will move a window in KDE/kwin. Is there a way to disable this for a particular application?

I know there's a lot of application overrides (click top left window icon > Advanced > Special Application Settings), but I can't find one to disable this alt key. The closest I can find is to disable global keyboard shortcuts.

Actually, the primary motivation for my question is now nil. I wanted to use the alt keys when running x2go, but I think the problem was in fact that the server wasn't using the alt+drag actions. When I switched from gnome-desktop to unity (by running sudo apt-get install ubuntu-desktop on the server), everything started to work as expected -- the alt keys now interact with the "guest" windows in x2go, rather than my client desktop's windowing system. –  gatoatigrado Apr 18 '13 at 22:58

In the KDE System Settings for Window Behavior, change the Window Actions for Inner Window, Titlebar, & Frame. With the modifier key set to Alt, set the left button to Nothing. You can also reassign the action to a different modifier key.
