You may not realize that MS Word offers some features known as keyboard shorts, otehrwise known as hotkeys. These speed up your work by offering a keyboard combination that takes the place of clicking a number of times.
Instead of going to File then finding Save, you can simply use Ctrl + S that does the same thing. Other hotkeys you might find useful;
Ctrl + P = Print
Ctrl + C = Copies highlighted text
Ctrl + V = Pastes the selected text
Ctrl + A = Selects all, such as all texts or even all files within the Windows Explorer window.
Ctrl + N = Opens new document.
Alt + Shift + D = inserts date
MS Word also provides some nifty short cuts for formatting text, See video below
