I've just started using Linux Mint 15 with Cinnamon 1.8.8 at work and when I press Alt+F1 the display zoom out and displays the workspace switcher.
How can I disable this shortcut? I removed the keyboard shortcuts in System settings → Keyboard → Keyboard Shortcuts that seemed relevant but with no effect. Then I removed all of them, but of course still no effect.
Update
The accepted answer worked for Mint 15. After upgrading to Mint 16 I also had to use dconf-editor as described by maosmurf below.
Best Answer
On my system (Cinnamon 1.8.8 on Linux Mint Debian Edition) I can disable it in the Gnome control center. Open a terminal and run
gnome-control-center
:Go into
keyboard
=> Shortcuts and select theSystem
section on the left:Now, change the shortcut for "Show the activities overview" click on it and then press Backspace to disable it.
It may be possible to do the same on Linux Mint 15 by going into
cinnamon-control-center
but that is not available on the Debian edition so I can't check.
