Here’s a list of most common shortcut keys(hot keys) used on Windows OS or in Windows applications. I use those to improve productivity. And you can image that when my colleges see I do something without using the mouse they ask, how did you do that? Well, these shortcut keys are not secret. You can find it in Windows help or documentations.

Note: WIN is the windows key, the one with a Windows logo.
