KeyBound is an intuitive key binding interface originally developed for Bongos. Using KeyBound, keys are bound simply by hovering over a button and pressing a key. KeyBound was based on the key binding system used by Trinity Bars.

KeyBound was converted into a LibStub library by Toadkiller, and given the new name LibKeyBound-1.0. The library now resides on wowace and is currently used by Bartender4 and Dominos.
