The function keys or F-keys on your PC keyboard, labeled F1 through F12, are keys that have a special function defined by the operating system, or by a program that is currently running. They may be combined with the Alt or Ctrl keys.
On some smaller keyboards, including those on many laptop computers, the F-keys may have a dedicated function such as changing the brightness of the screen, the volume of the audio, or other device-specific functions. On these keyboards, there is typically a separate Fn key that you can hold down to indicate that you want to use the key as a standard Function key. For instance, on the MacBook Pro laptop computer, the F12 key's primary function is to increase the audio volume. If this key is pressed while the Fn key is held down, the key will register as F12, and trigger any software functions that are configured to use this key.
If you would prefer not to press the Fn key to access your function keys, you can configure the keyboard to treat them as regular Function keys in your Control Panel or System Settings.
If your keyboard does not have a row of function keys, they are probably set up as secondary functions on other keys. Look for alternate labels on your keys or consult your computer's manual for more information.
An important keyboard button to pay attention to is the Wifi on/off switch. Unfortunately, numerous problems can occur when trying to connect your device to the internet but checking this key would be a good start.
