If you’ve been using OS X for any length of time now, you know the special joy of desktop “spaces,” what Apple calls its virtual desktop system. You can switch between them by hitting Command-Arrow (right or left) on your keyboard, or you can activate Spaces with the F3 key on most modern Macs. You can also reorder these Spaces around fairly easily.
But did you know you could add more Spaces? Delete the ones you have?
Well, you can, and it’s pretty simple.
When you activate Spaces with the F3 button, or a mouse gesture you’ve defined in the Mission Control preference pane, you’ll see your Desktops across the top of the screen, and (if you’ve checked the box to make it so) you’ll see the Dashboard full of widgets off to the left of that row.
In order to add more Spaces, hold down the Option key, and a little Plus button will show up to the far left of that row of Spaces. Click it once for each Space you want to add, and you’ll be able to add up to a total of 16 Dashboard Spaces for your computing pleasure.
To delete Spaces, all you need to do is click on the little iOS-style X button in the upper left of each Space. Click that, and that Space is gone, baby, gone.
