So how can you control the computer without your mouse? Well firstly, the easiest thing to do is use the ALT key and the ATL + TAB key combo. ALT + TAB lets you switch between programs and just pressing the ALT key on your keyboard focuses onto the menu options, such as File, Edit, etc.
The right-click keyboard shortcut is to hold down SHIFT and then press F10. That’s one of my favorite keyboard shortcuts because it comes in VERY handy and sometimes it’s actually easier to use the keyboard than the mouse.
There are some other handy Windows keyboard shortcuts that you should know in case you are stuck in a bad situation:
CTRL+ESC: Opens the Start menu (then use ARROW keys to select an item)
ALT+DOWN ARROW: Opens a drop-down list box
ALT+F4: Closes the current program window
ALT+ENTER: Open the properties for the selected object
