noob macro healing question

[Coltimar]

so ive run searches for various topics regarding healing macros and i know there are a ton out there. however, none seem to help me and its probably because im not very good w macros to begin with. anyhow, I 3 box atm and rotate my priest and druid as healers and so far ive used 1 healing macro w them that simply /targets my tank and does a castsequence. if other group members get in trouble i mouse over to the window and manually heal them. I dont want to do this anymore for obvious reasons and I was hoping for once I could get someone to just lay out their healing macros. I use a g15 keyboard so i'd like to use my g keys, modifiers would probably help too. I'm really just looking for someone to paste their entire healing macro setup so i can easily target other group members etc and heal them from my tank's screen without having to manually do it. Sorry if this wastes any of your time but it would be greatly appreciated and helpful to me! thanks!

I run a dedicated healer, but all 4 of my shaman have this.

G7-G10 are bound to 6-9 on my number pad. They do this:

G7
/cast [target=marlun] Lesser Healing Wave

G8
/cast [target=teetoe] Lesser Healing Wave

G9
/cast [target=jermayne] Lesser Healing Wave

G10
/cast [target=jackea] Lesser Healing Wave

They are all setup to heal my tanks target with Lesser Healing Wave at the press of number 5. My healer has a big healing button (4 different heals based on macro modifiers) bound to a key no other toons use. When grinding I have a dps macro (like my other 3 shaman) set to number 2. When on a boss fight I move the healing button to number 2 so I can spam it.

Hope this helps.
