if you own Surface Pro 3 tablet you might notice that the F keys functionality
is quit annoying. by default you have to press the Fn key along with the F key.
this can be very annoying when trying to work with software like Visual Studio.
to overcome this issue all you have to do is to learn single shortcut.
Fn + CapLock: this shortcut toggle the Fn functionality between the F keys and
the defaults keys (Home, End, etc.)
