You probably don't need the new Keymap to get this working.
But the new keymap specific to the team... won't interfere with other teams.

I recently started migrating my stuff so each team has their own Keymap.
Rather than a convoluted... when I press hotkey... send one thing to Team A, something different to Team B, etc.

It's easier to take a few steps now, and have it set up so it won't interfere with other stuff in the future.
