Keyboard shortcut to switch screens on split view I want to know if there is any keyboard shortcut to switch between splits screen in all new El Capitan.
Here is another partial solution. If you split your screen between two windows of the same program, e.g. Safari, then Cmd+` (backtick) will toggle between the two.

Caveats and Special Cases:


If for some reason this does not work, you probably don't have this shortcut enabled. The answer at https://superuser.com/a/187072 explains how to do this.
This was tested on High Sierra, but should work just the same on El Capitan, and so on.
