/out and /in are the specific commands or? Can you even do that if in combat?

Also, that always brings you to the start of the dungeon doesn't it? Your party could be really far along and then they'd have to wait until you manually walk to them I think....
As Kirraq said, just right clikc the green eye on your minimap. And yes while you will have to run back I find that I only get Combat bugs WoE and ET and both of them have portals leading up to the next boss.
