Clutch is a project mainly written in Lua, it's free.
World of Warcraft Addon that provides vehicle bindings.
Keybindings for vehicles in World of Warcraft.
I have most of my spells keybound directly so they are consistent between my two specs, sans the few that do change between my specs. This means most of my action bar is actually not bound--so I had to click my spells when doing the Argent Tournament jousting quests. This infuriated me, so Clutch was born to alleviate that mess.
Clutch is definitely in alpha. It currently works for my needs, but I am going to work on providing a user interface for others and adding per-vehicle keybindings.
You cannot change keybindings while InCombat(), so I have to find a way to work around this as best as I can so the users are aware of the situation.
The webpage and contact info will go up once there is a 1.0 (with full UI) build of Clutch.
