After getting a wireless Apple keyboard I sometimes experience that certain key sequences are not working.
When it happens, I launch Keyboard Viewer and there has always been some key shown as pressed. Pressing this key once fixes the problem — mostly it is the arrow keys (so now I just press them in sequence to fix the problem).
