6. In Adobe Photoshop, pressing the "F" key switches between the screen modes. These modes are normal, full screen, and full screen with no additional modes. Because there are multiple modes, you may need to press "F" more than once to select the mode you want.

7. In chat, forums, and other text-based communication, "F" is short for the swear word and is said or spammed when something bad happens.

8. In the phonetic alphabet, "F" is often pronounced as "foxtrot."

With U.S. QWERTY keyboards, the "F" key is on the home row, to the right of the "D" and left of the "G" key. See our keyboard page for a visual example of all keyboard keys.

Note

If the "F" key is not working on the keyboard, see: Some keys on my computer keyboard aren't working.

Tip

In ASCII, the uppercase "F" is "070" in decimal (01000110 in binary). The lowercase "f" is "102" in decimal (01100110 in binary).

Tip

Doing the Alt code Alt+70 creates a capital "F" and Alt+102 creates a lowercase "f" character.
