Here's a quick tip inspired by "garfalk" for you Mac users out there.... Gmail's Mac key combinations are almost the same for the Mac as for the PC with a couple exceptions. "Shift" clicking on the beginning and at the end will "select all". "Command" or "Apple" (same key) clicking will select items one at a time, allowing you to skip some. Also, "Command" + s will Save a draft. Those who tend to be "keyboard-centric" may find this helpful in reducing mouse grabs and clicks.
