How do I deactivate F1 and F10 keybindings?
In 11.10, I used Alt+F10 to maximise a window. I've used it so often, Ctrl+Alt+T and Alt+F10 have become a learned motion when setting up for work.
Since I've upgraded to 12.04, a single press of Alt+F10 opens up the File menu. Mashing it a couple of times does eventually maximise the window. It seems something is hogging Alt+F10 for a different mapping, yet when I look at System settings->Keyboard->Shortcuts, the only thing mapped to Alt+F10 is Maximise Window.
Where else could I look for mapped shortcuts so I can fix this conflict?
