Windows Keys
The keyboard has two keys that perform Windows-specific functions:
Windows Logo key and
Application key.
The
Windows Logo key opens the Start menu and performs
software-specific functions when used in combination with other keys. The
Application key usually has the same effect as a right mouse click. (See
your Windows manual for more information.)
