Whilst using Microsoft Word, there are a number of keyboard shortcuts which you can use so that your attention isn’t taken away from the keyboard to use the mouse. Here are some of the most useful ones:

Bold text: Ctrl + B

Italic text: Ctrl + i

Underlined text: Ctrl + U

To bring up the thesaurus: Shift + F7

To undo any action such as typing etc: Ctrl + Z

Select all the text in the document: Ctrl + A

There are more available for viewing through the Microsoft Office Help Menu which can be accessed by pressing the F1 button and typing in the search bar: Keyboard Shortcuts and then selecting: Keyboard Shortcuts for Microsoft Word.
