Do you put spacebar on the DNP list?

Sometimes when navigating I do need to jump, so that's why I put space bar on my pass-through list.
But then sometimes when chatting with friends, I do need to use space, so all my toons would jump up at the same time which looks funny.
Even worse, sometimes I chat while in combat (yes I do that >.<) because my master is on autoattack, and I just spam 1 nuke dps button until the mob is down. But when I press space, all the slaves would jump and interrupt the spell casting. Dumb I know, but sometimes I just forget that I'm in combat.
