So I was happily replying to a guildie in chat, typing away on the main's window, and my four slaves died. WTF??? Turns out I typed a word with the letter "c", which is my hotkey for flying mounts. All four of my slaves promptly jumped off their flying mounts, in midair, and fell to their deaths. Not my brightest moment, but now I'm really, really good about turning off key broadcasting before typing chat LOL
