5 druid macro to cast rejuv on entire team at once, then stack it. Help?

Hello, i'm new to isboxer and creating macros, so i would appreciate some assistance in what i would like to do.
I would like to create a macro for all five of my druids to cast rejuvenation on themselves on the first cast, then each consecutive cast each druid should cast rejuv on the next druid in line from themselves.
The end goal is to be able to apply as many rejuvs as are needed to soak up AOE damage or when panicking in fights.
So with 3 key presses i have 3 rejuvs on each druid, or with four i have 4.

I would much appreciate any assistance that could be given, I have tried to look through other threads but again i am new so i'm still trying to figure out what all the commands do. Thanks!

With IsBoxer you can have a hotkey send multiple steps.

For example lets say ` is your rejuvenation keymap. You can have IsBoxer send a 1 the first step, 2 the second step, etc. Then have macros on each druid 1-5 casting rejuv on party1, party2, etc.

There are many people here that can post great directions on how to do this, all I can do is point you to the wiki:

Got something to work, thanks :]
