Paladin + 4 Shamans

If i'm healing on my main window, I just use a healing addon like Healbot. You can set it up with left click=minor heal spell, middle click=chain type heal spell or alt heal spell, right click=big heal spell, or any variation of those. Also left, middle, and right buttons can also be combo'd with Shift, Alt, and Crtl, so you have up to 9 separate options. Decursing , dispelling, etc... is also doable with Healbot, even setting it up to call macros you have

I'm using:

Left, Right, Alt-Left, Alt-Right, Ctrl-Left, Ctrl-Right, Scroll Up, and Scroll Down.
As my binds.

Actually the Scroll Wheel are duplicate binds.
Trying to learn a bunch of no modifier mouse heals.
As they're faster, when in the thick of things.
