Sometimes Word documents contain a last blank page that seems impossible to delete.
Just place the cursor after the last character, press:
Shift+Command+Forward Arrow key
to select all after such last character, and then press the Delete key. That should delete the last blank page.
[crarko adds: There was a link to an example provided, but the document appears to have been moved or removed. Still, I have observed this over the years, and it does qualify as a Word annoyance to be combatted. This is a way to do that, and a little quicker than doing a lot of backspacing.]
