Quick Links
The Mission Control virtual desktops feature built into OS X is really nice, but the one annoyance is that moving windows to a different Space is a little tedious. You can right-click on the icon in the dock, but that's hardly a solution. Here's how to do it the easy way.
Just so we're all on the same page, normally you would use the three or four finger swipe up on the trackpad to activate Mission Control, and then drag a window to a new desktop.
But that involves swiping the mouse, and it's really kinda tedious when you do it a lot.
Luckily, there's an easier way.
Second Method, the Easy Way
All you have to do is click on the title bar of any window, and then use CTRL + 1 or 2 or whatever the number of the Space is.
There's no way that we know of to only use the keyboard to move a window, but this definitely helps. If you know of a better method, be sure to let us know in the comments.
