Change shortcut for switching to the next most recently used app among your open apps in MacOS

Go to System Preferences -> Keyboard -> Keyboard Shortcuts. Then, on the left side, select Exposé & Spaces. On the right side you will see the current keyboard shortcuts for Exposé and Spaces. If you double click on the shortcut command (literally double click ^1 for instance) you will be able to change this to whatever you want. Just do the key-combo you want to use.

So, once you double-click on the shortcut, it'll show it as editable. Then, press the keys you want the short cut to be, all at once, for instance press Apple and J at the same time, and it'll change the shortcut.

There seem to be two proprietary programs that do solve this problem, but there isn't a way to set it up yourself using a keyboard shortcut.

The two apps are Witch (as suggested by Buscar웃) and Contexts, in case someone wanted to check them both out. Witch costs $14, and Contexts costs $9.

I'm trying both to see which one fits my needs most as both offer a free trial.
