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.)
Function Keys
On the top row of the keys are the function keys: F1 to F12 . Function keys
are multi-purpose keys that perform functions defined by individual
programs.
