I am working with the new powexec_location slash command. It's amusing as hell.
What it works best with are powers that require a point-and-click, like Teleport and Recall Friend. My first useful bind is one that pops a teleporter upwards at max range with one keypress. (Still working on a similar bind for Recall and TP Foe.)
What powers that require such a point-and-click to activate could be useful if bound to a key? Pet summon?
