Why Alt Tab is Inefficient

Using Alt+Tab or ⌘ command+Tab to switch application is inefficient, because:

• 2 keys combination induces Repetitive Strain Injury.
• Using pinky, the weakest finger, induces Repetitive Strain Injury.
• You have to take half a second to eye-ball it to land on the window you want.

Here's more efficient and ergonomic solutions to switching apps/windows. Starting from most efficient solution.

One Function Key to Switch to Previous Window/App.

Some 80% of time when you press Alt+Tab, you are just switching to the last app/window. So, make that a single key press.

Set up single key (e.g. F9) to switch to previous window/app. (make this key do Alt+Tab)

One Function Key to Switch to Browser

There are 3 or 4 apps you use all the time. It's efficient to set a single key to switch to them, such as F5 F6 F7 F8. This way, you have muscle memory, and also, no use pinky to press Alt+Tab, and no need to glance at the screen to decide if you need to press Tab again.
