Angelic Feather Macro
This will put your Angelic Feather beneath yourself instead of having to actually click the screen with your mouse.
#showtooltip Angelic Feather
/cast [@player] Angelic Feather
Holy Word: Sanctify Cursor Macro
This will cast Holy Word: Sanctify at your current mouse location, again taking away the need for you to click the screen with your mouse.

/cast [@cursor] Holy Word: Sanctify
Heal Mouseover Macro
This will cast Heal on your currently mouseover target, this works with any targeted spell, I just used heal here as an example.
/cast [@mouseover,help,nodead] Heal
