Expand "Character Sets" in the top pane, and select your team. In the right pane, check the third option "In-game ISBoxer GUI toggle hotkey" and pick a hotkey. I use "Ctrl + Alt + /" as my hotkey.
Grid Set Up:First, we are going to configure Grid. To do this, type: /Grid Config
Click on Layouts, and then Custom Layouts. Click New.
Enter:
ToonA,ToonB,ToonC,ToonD,ToonE,ToonF,ToonG,ToonH,ToonI,ToonJ;NAME
1,2,3,4,5;5/5;NAME;NRSave this.
In the place of ToonA,ToonB etc, substitute the names of all of your characters.
With my setup, I have 36 names listed here.

The names on the first line, determine which names will appear in column one.
And the ;NAME determine it will be an alphabetical sorting.
The 1,2,3,4,5 on the second line tells Grid to display characters from groups 1 through 5.
You could go 1,2,3,4,5,6,7,8 if you wanted to run 40-man raids.
The 5/5 tells grid to display the names in five columns (first number) and to have a maximum of five names per column (second number).
Again ;NAME is an alphabetical sorting.
Finally the ;NR stands for No Repeat, which is a key -- since our toons appear in the first column, they cannot appear in any of the others.
If you were ten boxing, you could go with:
ToonA,ToonB,ToonC,ToonD,ToonE;NAME
ToonF,ToonG,ToonH,ToonI,ToonJ;NAME
1,2,3,4,5;5/5;NAME;NRWhich would get you five of your toons in Column A, five more in Column B, and the rest of the raid in Columns C, D, and E.
We will want to configure Grid a little more.
Type: /Grid Config
Click on Frame, and adjust the "Center Text Length". This setting determines how many letters of a characters name is displayed in the Grid frames. If you set this to "3", only the first three letters will be shown in the frame.
The Advanced sub-option under Frame has more options. We will want to adjust the Font Size, Frame Height, Frame Width and Orientation of the Frames.
Click on Layout, and set our alphabetical listing as the default for each of the Layouts. These are Party, 10-man, 25-man and Battleground.
Adjust the Grid Frame position, until its set up somewhere you like.
Once we're happy with our in-game setting, we will duplicate the settings exactly by navigating to: WTF/Account/Account Name/Saved Variables and copy Grid.lua. Then we will paste in each of our other accounts Saved Variables folders. This gets us the same settings for each account.
Clique Set Up:Clique is used to heal based upon clicks on a unit frame. Our Grid box will work, as will the party bar section of our interface.
Clique is very easy to set up.
Just go to each of the accounts which will be casting heals. Press P to open the spell book for the healers. If we're on a team with Tank + 3x DPS + 1x Healer, we only need to configure the healer to receive clicks. If our team is Tank + 4x Shaman, and they are both DPS and Healers, we will configure each of the shamans to accept clicks as heals.
With the spellbook open, click on the bottom tab. This opens the Clique interface.

Now go to the heal spell tab for your character. For Druids or Shamans this is the Restoration tab, for Priests this is the Discipline or Holy tabs, and for Paladins this is the Holy tab.
Move the mouse cursor over a spell and select a click, optionally including a modifier key. I recommend using Left Click with a modifier and Right click with a modifier. We can use Alt, Control and Shift as modifiers, which get us six heals we can configure on clicks. I would suggest not using Left Click or Right Click (without mods), because we will want the ability to select a toon and to trade with them, rather then casting a heal on them.
In general, you want to pick target based spells like Penance or Renew, and to not pick AoE spells like Holy Nova, as you can hotkey Holy Nova anyway without needing to target via a Repeater Region.
Using the IS Boxer GUI:Press your hotkey to bring up the GUI, my hotkey is "Control + Alt + /".
A moveable window appears in the top left of our screen.
I like to enable (check) KVM mode. With KVM mode checked, the current character will not click the box, but the click will be passed to our chosen target. This means none of our characters will change their target; if our tank is the current active/hot toon, we will not stop targeting the mob to use these heals.
Next, we use the arrow key to select the target of our Repeater Region. By target, I mean the character(s) who will receive our click. If the set up is Tank + 3x DPS + Healer, we will only want to pass our clicks to the Slot which the healer is in. If we were running Tank + 4x DPS/Heals, we would want to select "All Other Windows".
Once we have selected a target, click the "Add" button, which creates our window. Position the window so it entirely covers our Grid frame. And resize it to be as small as possible, but to entire cover the frame. As an option, some people like to only cover half the grid frame for passing mouse clicks, as this allows their Paladin tank to Cleanse by clicking the other half of the grid frame instead of passing the click on.
When you are happy with the position and size of the Repeater Region, press the Sync button. This will create a slightly shaded window in the same position on the recipient(s) screen(s). Check to make sure the Grid frame is entirely within the repeater region. In particular, we do not want the possibility of passing a click from our active character to the healer and having it miss the Grid frame and click beside it.
Go back to the tank character and click the Save button. We want to save the region as "Auto"; this means it will automatically load, whenever we load this character set in IS Boxer. If you pick a different name, you will need to manually load the region each time you start up.
Press the GUI toggle key to close the GUI interface.
You will want to repeat the process on each of the other toons, so no matter which toon you are on, you will be able to click the grid frame to have the healer heal the character you clicked on.
