Addon - qUserKey

[Dead_Dwarf]

Found this addon while trying to get my bindings all setup for my boxing setup. It lets you bind a key directly to a spell. Other addons may do this I dunno. I found it useful and thought I would share.

I use a similar addon called BindPad. Its great for spells/macros that you don't want on a bar but want a keybind for.
