How to jump between Spaces on OS X when some are Fullscreen?

I'm with @Tetsujin on this one. I never use fullscreen apps.

However, you could do what you want with Total Spaces 2.

Make sure to check the compatibility info below the download button.

Let's say you use 3 fullscreen apps:

1. Close the full screen apps and create 3 extra spaces.
2. Once you got those spaces, give them shortcuts In Total Spaces 2.
3. Once the shortcuts are created, remove the extra spaces
   • Total Spaces will remember the shortcuts.
4. Then add 3 new columns, but don't press the add desktop button.
   • This essentially reserves spots for the full screen apps

I'm afraid it cannot be done natively.
The closest you can achieve is to jump the last regular desktop with Ctrl ⌃ [num] then
Ctrl ⌃ → from there.

The difficulty is that fullscreen apps don't have a Space number, so you cannot add a shortcut key.

My personal solution is to simply never use fullscreen apps, I find them more trouble than they're worth.
