When you save a document in Word 2013, it also saves the location of the cursor. However, when you open a saved document the cursor will be back at the top. To change this all you have to do is press a keyboard shortcut and it will bring the cursor back to its last known position when the document was last saved.
To activate the hotkey, press Shift + F5 simultaneously. If the combination is pressed once it will bring your cursor back to the last position. If pressed multiple times it will scroll through the last few known positions.
While it doesn’t have a lot of other uses, I found this to be a handy tip for anyone working on saved documents in Microsoft Word.
