In keeping with last week's theme of shortcuts, have you ever been in a Skype meeting and had to mute your mic real quick. Or maybe you had to unmute your mic, because you have been talking for the last five minutes and no one is answering your questions. Well luckily there is shortcut key for this - win + F4. It will unmute and mute your mic. Also try out win + F5 to turn on and off your camera. (FYI on some keyboard turn on the function (Fn) lock to use the Function keys). We should all try to use our camera as often as possible as the majority of communication is nonverbal (55% to 93% depending on the source). When we don't use our camera, we are missing half the story. Another way to think about it is, it will take twice as long to get your point across. In addition to shortcuts for muting and turning on the camera, Skype has many other shortcuts. I have listed my favorites below.
