How do I change the labels on the hotkeys?

[Vestrial]

Ive fought with the UI tool for a while now and cant even seem to find the hotkeys, (I did read the faq and doc that came with the game, neither of which seemed terribly helpful) so can someone tell me how to change the labels on my hotkeys? (would rather learn how to do it myself as I may change my binds again after a few levels and dont want to have to come bother people here again)


thanks,
