Bonus tip: These keyboard shortcuts work when you’re in Mission Control, too, so you can easily make any desktop the main, current desktop in Mission Control without Option-clicking on its thumbnail.

Q: I separated multiple projects in my app by putting their windows on different desktops. Is there a quick way to gather the scattered windows back onto one desktop?

A: You can quit the program, relaunch it, and reopen the windows.

Or, if you’re willing to sacrifice some of the desktops where those windows are parked, you can do it from within Mission Control. First, go to the desktop you want the documents on so it will be the main one in Mission Control. Go into Mission Control and hover over a desktop that holds other windows from the app until you see the Close button. Click it, and any windows on that desktop move to the main desktop. Repeat for the other desktops.

Q: Should I assign every application to a specific desktop?
