Hiya! Anali asked for me to post this here, so I will repost what I read elsewhere. I didn't come up with it!

A caveat on mouseover healing: it seems bugged sometimes. Recommended steps are to be in raid frames and not have your mouse hovering over debuff icons, since it seems to make you lose your target and heals you instead of your target. Hopefully Trion will fix this or improve it soon.

this thread is the motherload of info on macros: http://forums.riftgame.com/showthrea...ft-Macro-Guide

*MouseOver Heal Example*

suppressmacrofailures
#show Basic Heal
stopcasting
cast [ctrl] @mouseover Heal Over Time
cast [ctrl] Heal Over Time
cast [alt] @mouseover Big Heal
cast [alt] Big Heal
cast @mouseover Basic Heal
cast Basic Heal

This makes all error messages from things not being ready to cast not show up (supress failures).
Then it turns the macro icon into the icon of your basic heal, so you know wtf it is. Then, it makes your heal over time spell fire off when you have your mouse physically hovering over a person's raid frame, group icon, or even physically over their actual in-game character.
When it isn't over someone, however, and you press control, it will cast the heal on you.
Then, when you hover your mouse and press ALT it will do your big heal. if you press whatever keyboard button is associated with your heal over time, it will do that with your mouse hovered.

There ya go! Be careful to watch it, as it may bug out on ya though. bug report it in game if it breaks on you so they can work on fixing it!
