Use autohotkey to bind multiple attacks in sequence to one mouse button, I use the back button in this tutorial. Great for Ret paladins or monks and many other classes.
Script for Sarah Adams = http://goo.gl/TrgjR7
right click on edit script, delete everything and put in these 2 lines:
IfWinExist World of Warcraft
XButton1::Send, {Numpad5}{Numpad6}{Numpad7}{Numpad4}{Numpad3}
Save the file, then right click on the autohotkey icon and hit reload script. You are on your way, check documentation with the product to make more macros and bind them to other keys.
Get autohotkey from autohotkey dot com
