I use a toggle for Jamba Strobing.
If I switch from one toon to another, they automatically follow the new toon.
If I press the arrow keys, then the toons move forward/backward or strafe left/right as I have configured.

Pressing my follow keymap doesn't seem to do anything.
But turning follow strobe on, and then off (or leaving it on) and follow resumes.
When I want to break follow, I make sure my MR (G-key light is off, so strobe is off) and then press an arrow key.
