it depends on what microsoft software you're using; if you're using Word, its towards the top left... its a blue back arrow. clicking the drop arrow allows you to choose what action you want to reverse.
you can assign shortcut key to application by right clicking and choose properties then under shortcut key assign something you will remember
F1 (usually found in the top most row of the keyboard, towards the right of ESC button)
If you're using Microsoft Word: Ctrl and F2 (whilst still pressing the Ctrl key). Alt - F - V will also work.
That really depends where you want to write it - in what program. For example, in Microsoft Word or Microsoft Excel, you can go to character format, and select "superscript". The shortcut key (at least in Word) is Ctrl-Shift-Plus.
