Simple addon, all this does is speeds up triggering actions by making them happen when you press a key or press your mouse rather than releasing them. It's setup to work with all of the default Blizzard action bars as well as totem summoning and recalling. It will automatically work with any addon that uses the default Blizzard system for key bindings (Game Menu -> Key Bindings). Even if an addon doesn't work with Speedy Actions I can add a module to make it work, just see below.
There is no real performance cost from using this addon either, the work it does is out of combat and while in combat the only "cost" is that of executing a key binding.
Slash commands: /speedyactions (/sa, /speedyaction)
<addon> does not work with this?!
If you find an addon that does not work with Speedy Actions, post a comment with the download page and I will work on making a module to make that addon work with Speedy Actions.
<addon> is already supported but a button didn't work
Should you find an addon that is already listed as working, but a button isn't being sped up then do this:
Mouse over the button that isn't working and run /script print(GetMouseFocus():GetName() or "<unnamed frame>") then post the addon name and the results of the script and I'll get it fixed
