After experimenting with using CAPS to toggle the Fn key between icon tasks (like brightness and mute) and function tasks (like F1, F2), something went haywire with my Home and End keys on my Type Cover. I tried a System Restore, but it didn't solve it. For example, in Word 2013 the Home key now does nothing, End launches the numbers and letters to select items on the Quick Access toolbar and menus, Ctrl+ Home inserts left and right squiggly brackets, and Ctrl+End shrinks the window. I use the Home and End keys constantly to move around on the page. Help!
