I setup my normal arrow keys so that they only control my slaves and have no effect on the master.
I did this by removing the up,down,left,right from each accounts keybindings.
Replaced forward, backwards, strafe left, strafe right with ctrl+alt+shift+up, down, left, right.
then have a movement keymap that houses all my tweaks. So when I press up on the master, my slaves get ctrl+shift+alt+up
For portals, it's simple.
This shines for movement in fights and getting out of stuff opposes to just using follow to move them with the master.
I have down mapped to my naga to quick follow breaks.

I'm pretty sure there is a variable keybind option to do this as well but I "made" this fix up for myself a very long time ago and just stuck with it.
