KeybindVisualizer is an AddOn that displays your keybindings as you press them!
Use /showbinds to toggle showing your binds.
This is a work in progress. I'm just starting to delve into LUA so please don't mind the sloppy coding. I'm sure this could probably be done in a much more optimized way but for now this works for me. I had thought about trying my hand at writing this a while back but never got around to doing so. There was a recent post on the official WoW forums asking if there was any AddOns like this around so I decided to finally give it a go.
Keep in mind, this is a work in progress so please don't expect a fully polished AddOn right out of the box. I will try to keep working on this in my spare time but the basic framework is here.
And finally, any and all input and criticism is welcome.
