I'm running Ubuntu 12.04 with Unity3D.

When I press Alt+Enter (a keyboard shortcut used by a number of things, especially Sublime Text), the Compiz magnifier is launched (creating a box around the cursor, and zooming the contents of the box).

I tried to change the keyboard shortcut in CompizConfig Settings Manager (the "Magnifier" effect). I changed it to Ctrl+Alt+Space, which is working for me. However, Alt+Enter still triggers the effect.

If I disable the effect, it stops. So I know it is the magnifier effect. I just can't figure out why Alt+Enter is still triggering the effect even after changing the shortcut.
