By using keyboard instead of mouse, saves a lot of time, It helps us to work faster and more productive. Instead of moving mouse from one place to another, just use single keyboard shortcuts.

For example you just need to hit Ctrl+C to copy something and Ctrl+V to paste instead of right click on what you want to copy, then click on the copy function then hover to the place you want to paste it, right click here and click on Paste. Wow how long it is to just presentate it, imagine how longer it is to do instead of using keyboard shortcuts.
