F11 key

The F11 key is a function key at the top of almost all computer keyboards. The key is used to Enter and exit fullscreen mode in all modern Internet browsers. As mentioned below, F11 also has other uses depending on the computer and program.

How to use the F11 key

Open the program that uses the key and press F11. If the F11 key also has an icon on the key, it indicates the key has a secondary function. To use the secondary function, press and hold down the Fn key, and while continuing to hold the key, press F11.

If, when pressing the F11 key, the secondary function is performed (e.g., mutes audio), the function keys are the secondary function. For example, on an Apple computer, to press F11, hold down fn, and press F11.


If the FnLk (function lock) is enabled, the keyboard acts as if the Fn key is being pressed until it is unlocked.

Information about the secondary function is found in the below secondary function of the F11 section.
