I know this has been posted before but apparently, I couldn't reply on the old topic anymore. Anyway, lots of people love Quicksilver but I've found Spark an easier alternative. If you want to remap keys, make shortcuts and get the most out of your external keyboard, I highly recommend this old but still very useful (and free) app. What I've done with it: -added shortcuts to control volume, bluetooth, sleep modes, eject CD and itunes control -remap the | button as delete in my 3rd party keyboard -auto launch files using a keyboard shortcut http://www.shadowlab.org/Software/spark.php
