Microsoft Edge full-screen mode(How-to guide)
EDIT (October 18, 2017): Since the Windows 10 Fall Creators Update, you can now press the default F11 to make Microsoft Edge go full screen.
A lot of regular Microsoft Edge users and Windows Insiders have been requesting a full-screen mode for the Edge browser since it was first introduced. Unlike other browsers (and non-UWP apps) pressing F11 doesn't activate a full-screen mode in Edge. Microsoft has been aware of this request for a long time.
However, with no official word from Microsoft, it has come to light on Reddit that there is a full-screen mode in Microsoft Edge and other UWP apps. Just press Windows key + Shift + Enter.
