A: It’s a cinch: when you’re in Mission Control, move your cursor to the upper right corner of the screen and click the New Desktop tab that slides out from the edge of the screen. If your Dock is on the right, you can access the New Desktop tab from the upper left corner instead.

Q: Is there a quick way to create a new desktop for a specific window?

A: Say you want to put iCal on its own desktop. Instead of clicking the New Desktop tab and then dragging the iCal window into it, drag the window from the main Desktop to the upper right corner of your screen and drop it on the New Desktop tab. Voilà! If you drag the app’s icon instead of a single window onto the New Desktop tab, OS X moves all the windows “attached” to the icon onto the new desktop. (This works to move them all to an existing desktop, too.)

Q: Can I create as many desktops as I want in Mission Control?

A: You can create up to 16 desktops. You’ll probably find that, as a practical matter, desktop control becomes unwieldy before you reach that limit.
