Hand of Protection (HoP) Macro
I use this a lot on my squishies – they love it because most paladins don’t use it, unfortunately.
BoP Aggroing Party Member This BoPs your current targets target (i.e. use it if a party member pulls aggro from the tank on your current target). If you are not partied it will BoP yourself. Pressing it again will cancel the BoP if cast on you (get rid of the BoP on yourself to resume DPS or if the BoP was accidental).

/raid %T is protected!

Tanking
Divine Shield This Macro will allow a tank to cast Divine Shield and remove it in two clicks. This will allow a tank to remove all debuffs, DoTs, fears, and other harmful spells and then remove the shield so you can pick up aggro. This can also be used with blessing of protection and Divine Protection.
