I really like this feature, for multiple team setups.

If you open up the Toolkit, for configuration of your character sets.
And then click on one of the character sets.
In the bottom left frame, you have Key Maps, along with all the Key Maps that apply to that team.

If you click on Key Maps, in the bottom left frame, in the bottom right frame you can "White List" various Key Maps for your team.
The Key Maps you select here, are the only ones which can apply to your team/character set.

The wizard gives you General, FTL DPS and Control Keymaps, each with a bunch of mapped keys within.
I have things that apply to all teams always, in Control (applies whether Keymaps are enabled or disabled)... things like: when I swap from one character to another, do this...
I have things that apply to all teams, but only when Key Maps are active in General... things like Shift F10 = Shift F10 to all windows (which happens to be my Ground Mounts).

I generally copy the FTL DPS Key Map in its entirety, and then paste and rename it after the Character Set.
Then the original FTL DPS Key Map is set to not apply to the character set, but the copy is.
So I can make changes, such as "4" being a round-robin within the character set, without having conflicts with other sets; if you make "DPS 4" within the default FTL DPS Key Map a round-robin key, your other teams might not like that.



In general, run the wizard for the new team.
Get all the basic stuff done.

Then create a Key Map that will only apply to this team.
Set your Key Maps, as above.
Then modify whatever you want, within the Key Maps that apply to your new team without interfering with existing teams.

You can have a Spam Key.
It can send "1" to your first class/tank.
And "2" to your other guys.
Or however you want to configure it.
The two-step macros by Mercurio are phenomenal for mixed classes.
Mash one key, which alternates between two macros for each class on your team.
