How to delete or alter an event listing?

I've checked the knowledge base, I've checked the stickies, I've searched and searched and can't find an answer.

I have to cancel and reschedule an event of mine. How do I do that? There's no way on the event editor on the website to edit the time/date and I don't see a cancel button.

EDIT: Dangit, nevermind. There's no delete button on the event editor... but there IS one one page before. Awkward user interface, ho!
