For many years keyboard shortcuts have been making life just a little simpler for many people. In some cases, with the press of a couple of keys you can replace several clicks with the mouse. In other cases it is just easier to use the keyboard for commands rather than the mouse. Here is a short list of the best keyboard shortcuts that have made my life simpler.
Control + A: Select all the files in the window
Control + C: Copy (instead of right click> copy)
Control + V: Paste
Control + X: Cut
Control + P: Print
Windows key + L: Lock screen (if you have a password then it will be required to unlock)
The Windows key is between the Control and Alt key.
There are many more shortcuts for many situations, but these are the ones I use regularly.
