There is a great and pretty handy little ‘Go Back’ shortcut in Word.
To illustrate its potential use: if you’re working away on page 4, then move to page 23 to copy some text ‘Go Back’ can return you to the previous editing location (page 4) quickly. Simply press…
This keystroke will cycle through your last three editing points and the fourth cycle will return you to where you started.
The neatest thing about Shift+F5 is that the last edited position is saved with the document. This means as soon as you open a document, if you use Shift+F5 you’ll jump back to where you were working on it last.
Note: Ctrl-Alt-Z will also Go Back (3 max).
