My keyboard stopped repeating - how to fix? I have both an internal and external keyboard but the key-repeat has stopped working.  I've tried changing both 'Key Repeat' and 'Delay Until Repeat' as shown below but no setting seems to be helping.

Option 2. Download Mountain Tweaks (I assume you're on Mountain Lion, if not, download Lion Tweaks) and click the "Yes" option for "Enable Repeating Keys":
