Open ISBoxer Toolkit.

On the top, under Character Sets.
Click on one of the sets.
On the left it should have the set selected.
On the right pane, check the 3rd box down. It reads, "In game ISBoxer GUI toggle hotkey".
To the right pick your hotkey.
I use Control + Alt + /
Fizzler uses Shift + Alt + G
You can set it to anything you like.

You'll need an addon to interpret your clicks.
If you use Grid, you'll also need Grid Custom Layouts.
Type /Grid Config
Click on Layouts and then Advanced.
Enter ...... order=NAME;
This orders the Grid frame alphabetically.

With the Grid option, you'll also need something like Clique.
I use Grid + Clique, but there are other options.

You can go with Healbot, there is an alphabetical setting.
Or you can go with Vuhdo.
Neither Healbot nor Vuhdo will need Clique, they interpret the clicks on their own.

Position the frame in exactly the same place on every client.

Use your hotkey for the IS Boxer Repeater GUI interface.
I generally check KVM mode, so the click doesn't change my active toons target.
Pick the client(s) you'd like the clicks to pass to.
I believe the choice is all others, or a specific slot.
If you have two healers you could do a repeater for each fairly easily.
Drag the window over the Grid frame and resize to your liking.
Hit the Sync button to ensure the repeater region is the same on the healer (covering their Grid Frame).
If need be, adjust the position of their Grid/Vuhdo/Healbot frame.
Save it as Auto.
This means it will work without needing to load it, just starting up ISBoxer in the future.
Close the Repeater GUI, via your hotkey.


*Edit*
You can create a repeater region for every member of your team, who is not the healer.
That way, no matter what toon you are on, you can click heal from that toon.

You can also use modifiers with your clicks.
I like to have normal left/right clicks do nothing, so my priest can target a toon or open trade with them.
You can use any of the buttons on your mouse, such as forward thumb button.

I'm using:
Forward Thumb = Holy Nova.
Backward Thumb = Penance.
Alt Left = Renew
Alt Right = Flash Heal.
