Most of you probably know that you can use the keyboard combination "alt" + "tab" to easily swap between different computer tabs (programs/processes).

You could also hold alt and just press tap "tab" to select the program you would like to pull up.

Something you might not know, or you've probably never used is the combination "alt" + "shift" + "tab". It does the same thing as alt tab, however the order that it goes through the tabs is reversed.

So if you tapped tab one too many times, you can just hold down shift (together with alt) and press tab one more time to go back.
