Scaling problem

Libreoffice 5.1.4 on Windows 7. I made the mistake of changing “Scaling” to 400%. Now everything is so large on the screen that I can’t change it back. Going to Tools, Options then View, the Scaling box where I should be able to change the setting is hidden and I can’t increase the size of the window large enough to get it to show. Any idea how to change the setting back?

With Tools/Options - View open press alt+a

type 100 & enter.

Thank you so much, it worked. I was about ready to uninstall and reinstall so I’m glad I checked here for an answer first. Thanks again.
