What is a functional key?

The function key is the keyboard key, usually for a type of computer that runs or performs various programs or aspects of the program when pressed. These keys act in a different way than standard input keys for individual functions such as letters and numbers that generally indicate a letter or number to be entered into the system regardless of the program used. The exact purpose of these keys is usually marked with a program with which the user currently interacts, although certain features are somewhat standard in different programs. The function key is usually marked with "F" or "FN" on the key and often also for easy identification.

also called "F-keys", the function key works so that the computer program shows what operations will be triggered when the key is pressed. While for most computer programs it is possible to determine "hot keys", the function key tends to be generally recognized as separate from other keyboard keys and used for different purposes. These functions can bI can allow the user to change the function of these keys to do different things.

Although different programs create different purposes for different function keys, there are certain common uses that can be used for different programs. For example, many web browsers allows you to press F5 to restore the website. F3 can usually open a search field and many different programs use as a function key to open the menu or the help window when using the program. Most Microsoft® Windows® versions allow the user to close the currently selected window by pressing Alt+F4, and if the F8 is pressed when Windows® starts, it will start in safe mode.

Other Microsoft® products also use functional keys quite amazing for a number of different features. For example, in Microsoft® Word® runs the F7 Akontrol spelling in the currently open document and in PowerPoint® F5 Slet go of the picture. The Mac OS® operating system often provides key features over one of the many options, such as the speaker volume and the monitor.

Function keys are also commonly used in basic input/output systems (BIOS) when you start a computer that allow a number of functions. F10, while in the BIOS, it usually stores and ends the program, restart the computer in the process, while the F7 can often load the optimal BIOS configuration for the computer. Most keyboards include a number of different keys for different functions, and some keyboards contain liquid crystal keys (LCDs) that may indicate an action within a program that will press the function key.
