I use this shortcut regularly inside IntelliJ IDEA. And now it is stolen by something else.
It is not displayed in the Keybaord settings, and I couldn't find it with gconf-editor.
Any ideas what app is that and/or how can I change it?
I found the problem! :) Turned out that I had pressed the F-Lock key on the Microsoft keyboard. And it doesn't have any indicator lights so I didn't know. And restarting the computer had no effect on it either.
