A lot of PC keyboards and a good number of laptops
will usually have a couple of hotkeys somewhere to control the system
volume, either by pressing an ‘
Fn’ qualifier key and a number
key, or some extra added on buttons. You might even have a nice little
dial or slider to handle it for you. Sometimes there will be a function
in the provided driver or software that shows the volume level status in
a nice on-screen display. But if it isn’t available, you’re stuck with
the basic Windows volume control options using the icon in the system
tray. My Logitech keyboard has a dial and a mute button but nothing to
display this on the screen.
