As you probably know, the Start menu in Windows 10 has two sides. There’s the traditional list of your apps on the left, and tiles on the right. If you start typing, you’ll discover that you can navigate the left side from the keyboard. Too bad you can’t navigate the right side if you’re a keyboard nut!
Actually, you can! Just hit the Tab key. Now the arrow keys move around the tiles. Hit Enter to open one, and boom—you’re in.
