You can easily shave time off your computer work with shortcuts. They are best in Microsoft, but you'll find them in Google and Apple.
If you haven't explored shortcuts in Apple, just click one of the file menus and it will show you the shortcuts to activate with the command key.
Google Docs or Gmail? Go into settings and activate shortcuts. Then print the list and memorise it.
Here's the problem: Using the mouse. It's click. Click. Click. Move it here, slide it there. You know the standard shortcuts with the Control key in Windows. Contol + C is copy. Control + V is paste.
But have you ever noticed in a Microsoft program letters or numbers popping up on the ribbons/menus? That means you've hit the alt key by accident.
