That always bugged me with the Teleporter Stones.  I reckon that pick-up should be the default action with the Teleporter Stoens and that you can use the Skill hot-key to use it.  Although, what about the Stone you leave in a permenant place?  It would suck having ot pick-up and drop that everytime you wanted to use it.
Damn it.  Why can't mice have 37 buttons to make life easier?
