Since Wednesday I can no longer use ⌘2 as shortcut in any application on my MacBook Pro. I've quadruple checked Keyboard Shortcuts in Settings and I have nothing there. ⌘ and any other key works fine.
Today I discovered that with an external keyboard attached, I can use ⌘2 by using the 2 key on the number pad, but not the 2 in the number row.
Ideas?
