What's the word for...

So "refudiate" and "vuvuzela" are the popular words of 2010, but there are words that I wish to know to describe certain popular scenarios or activities.

In these days of multitasking on the computer, with instant messaging a popular form of communication, a typical computer screen can have multiple chat windows up at any given time. Eventually, you end up typing a response intended for someone but sent to another. Hopefully it will not be something like "I really do not like Mr. So-and-So" and sent to Mr. So-and-So! The chance of having such a mistake increases greatly if you use Microsot's Office Communicator. A new chat someone initiates with you simply jumps to the front and commandeer whatever chat you may have going at that time. So, what do you call such a mistake, which involves sending an intant message to the wrong person? Instant mistake? Lame AIM? Mis-chat?

Another typical office faux pas involves conference calls. Leo Laporte wants everyone, or at least everyone who listens to his many podcasts, to use GoToMyPC or GoToMeeting, but I don't know anyone who does. I do spend a good percentage of my time on conference calls, the old-style one with everyone on a phone, voice-only conference, that is. Unless you use some old phones from the late 90s, your phone probably has a mute button. Maybe you have a sudden urge to eat potato chips during the conference call, or need to chat away on some obtrusive OCS window, that is, typing noisily. So you have the mute button pressed. Then suddenly your name is mentioned in vain on the conference call and you need to defend yourself, verbally, of course. You rant on and on about how much money you saved the company by whipping up some kick-ass KiXtart script blah blah blah for twenty-five minutes. Then you realized you were still on mute! What do you call that? Malk (short for mute-talk)? Tomute (talk-on-mute)? Mutestake?

As Foreigner once sang back in the 1980s, I want to know what that word is, I want you to show me.
