In Addressbook I want to create a keyboard shortcut for the Menu entry Delete Group using the key combination option-command-delete.
So I went to System Preferences --> Keyboard --> Keyboard Shortcuts and added an app-specific shortcut entry for "Delete Group". But when I tried to assign the key combination option-command-delete, my input wouldn't get accepted. (Combinations with letter like option-command-D work, though.)
How can I enter a shortcut combination involving the delete key?
