Don't want to point out the obvious, but most M$ enabled keyboards (the ones with the little windows 'flying panes' icon) also has a key that does this. It's the second key to the right of the space bar and has a little 'icon-arrow and menu' graphic. It won't work on the desktop (ie to set display properties) but it does work in IE and windows file explorer, the same as Shift+F10.
