The F keys are function keys. They perform different functions in different programs. F1 is used as the "Help" key throughout Microsoft Windows and Office programs. F3 will start a search feature. In the old days (that would be the 1980's and 90's), the function keys would activate menus or other shortcuts. Some programs came with a cardboard template that surrounded the F keys to identify what function each key performed.
These are known as "function keys" and it depends on what program and operating system you are running. For example, F1 usually corresponds to the program's "help". If you press Alt, these have different commands. For example Alt+F4 closes out of the current program. If you have a keyboard with an Fn key, it corresponds to different commands as well. These commands depend on your keyboard though.
Those are functions keys and, depending on the program being used, can vary in use. There are some general function keystrokes that stay the same from program to program such as F5 being refresh, Alt+F4 being close window, and F1 meaning help.
It depends - whether you simply press the function key on its own - or combine it with the 'Fn' key, and the results may vary on different computers. For example - on my Toshiba - the F1 key on its own starts the 'help' program. Combining the F1 and Fn keys together 'locks' the computer (so you can leave the machine on without anyone seeing what you were doing). You need to re-enter your password to continue working.
For a more accurate answer, you would need to check the manual that came with your computer. It will usually have a tabel of all the function keys on your machine, along with their uses.
The "Function Keys" are typically used by programmers to access application-dependent functions. F1 in Windows is universally known as the "Help" key, although not all programs (notably computer games) conform to this rule. Each program can choose to assign a value to any Function Key, which can be further modified by almost any combination of meta-keys (Shift, Control, Alt, and Windows on a Windows keyboard, for example).
Alt-F4 (hold Alt and press F4) is a system-level command that advises a program to close in Windows and Linux. Linux also defines other Function keys, such as Alt-F2 to bring up a Run dialog. Other than system-level functions, any application can use any "Function Key" for any purpose it deems. Not all keyboards have F11 and F12. Older keyboards only had 10 such keys.
Function keys were originally designed to allow "generic" buttons that would change their function based on the software running. For example, the "A" key has a well-known feature, expected feature (sending an "A" character to the program). Similarly, Enter is expected to insert a new line or complete a command, or in some other way signify a completion.
The functions of the function keys vary per application. For the most part, they have no fixed functions. Here are some of the common functions of those keys.
F1 - This is often the help button in a number of programs.
F2 - This is sometimes used as a save or load button.
F3 - This a save or load in games and Find Next in browsers and various text editors.
F5 - Browser and Windows explorer refresh. Quick-save in games.
F6 - Browser and explorer toggle to the address bar. Quick-save in some games.
F8 - Quickload in some games.
F9 - Quickload in some games.
F11 - Browser kiosk (full screen) mode.
All keyboards are different, specially on a laptop. On my laptop, F1 is a help button and F12 is my WIFI on/off switch.
They are the function keys.
Most keyboards have 12 function keys. F1-F12 (all the keys with the letter 'F' and then a number).
The Function keys should all be on the top. ( F1 to F12 )
If you mean the function keys on the keyboard, they don't have a standard definition. The usage of the keys depends on the specific program. F1 is usually standardized as the help key; the other keys depend on the program you are using.
Computer keyboards many keys. All the different key are part of the following categories: 1. Control keys (like Ctrl & Alt) 2. Typing keys ( A to Z and .,?!£* etc) 3. Function keys (F1 to F12) 4. Numeric keypad (the number keypad on the far right)
Function keys are located on a keyboard in the top part. It starts from F1 and ends by F12. Some keyboards don't have function keys.
These are function keys that allow you to perform generic functions in many different programs. For example, F5 will refresh the page in Google Chrome, Firefox, and Internet Explorer. ----------------------------------------------------------------- The function keys (F1 - F12) are basically shortcuts, which can be used to perform a task quicker on a computer. For example: If you wanted to quickly refresh a website, then you can press F5. If you wanted to view the web developer source code (Something useful for website developers), then you can press F12. These shortcuts will also work for different programs, depending on the configuration (settings) that are applied or set up.
F1-F12 are often used to quickly access a part of a program, such as F12 opening developer tools in Internet Explorer.
Q,W,E,R,T,Y,U,I,O,P. These are the letters of the alphabet. Other keys include [ { ] } \ |

If a program uses the F1-F12 keys as shortcuts and if you click them and it changes the sound or something, hold FN and it will act as a shortcut

Typically, The "F-Keys" as they are known, are specific to the particular application you are using (firefox, Photoshop... etc.). As a general rule, the F1 key brings up some help documentation.
