TapDex 3.1.1
TapDex gives you a quick and simple search interface to your Mac OS X's Address Book. Tap the hot key and up pops a search window, start typing to narrow down your search.
TapDex is small, fast and takes up very little resources. It is designed to run in the background (yes, it can run without a Dock icon) and activated with a hot key. Customize it to auto-launch on log in and all your Address Book contacts will always be one tap away!
