Personally, I use Pitbull4 with mouseover healing instead of click healing and do the configuring in HKN. I use a lot of mouseover in my setup.

2 or 3 + Mouse over the portrait frame = Greater Healing Wave.
2 or 3 + Mouse over the bars = Healing Wave.
2 or 3 + Mouse over the debuffs section {right side of the bar} = Healing Surge.

Ctrl + Insert {one of the keys on my Naga} + mouse over bars for rez + Riptide out of combat or Chain Heal in combat.

I also have "hardcoded" cleansing set up to somewhat mimic Decursive and additional mouseovers for interrupts, purges, long cooldowns and short cooldowns as well as procs and emergency buttons.
