I got a quick question

[Bay]

While multiboxing how can I make one of the smaller screens swap out with the main screen?

Go to pwnboxer, you have configure Fast game switch. You need to decide what keys you want to use for which game.
I dualbox, on game 2 I have F2, just need to press that to change, And to change back same key.

Good luck

PwnBoxer can do this easily as Beda stated (nice post btw Beda!) - With 5 boxing, I personally have Shift F1 through F5 set up to each of the windows. The F key corresponds to the window number. This works well with the targeting macros I have (F1 being target my paladin, which is my main screen)
