Function Keys
Function Keys
Function keys (F1 through F12) are special keys located at the top of most keyboards that perform specific tasks determined by the active program or application. They can be used to access commonly used commands, such as saving a file or printing a document.
What does Function Keys mean?
Function keys are special keys on a computer keyboard designated to perform specific tasks or shortcuts. They are typically located at the top of the keyboard, above the number keys and below the F-keys. Function keys are often labeled with abbreviations or icons that indicate their functions. For example, the F1 key may be labeled “Help” or display a help icon, while the F5 key may be labeled “Refresh” or display a refresh icon.
Function keys were originally designed as a way to provide quick and easy access to common commands or tasks. For example, the F1 key was often used to Open the Help menu in software programs, while the F5 key was used to refresh the current page in a web browser. However, as software and operating systems have become more sophisticated, the use of function keys has changed.
Today, function keys are still used to perform common tasks in many software programs. However, they are also often used to control hardware devices, such as controlling the volume of speakers or adjusting the brightness of a monitor. Some keyboards also have additional function keys that can be programmed to perform specific tasks or launch specific applications.
Applications
Function keys are important in technology today for several reasons. First, they provide a way to quickly and easily access common commands or tasks. This can save time and improve productivity, especially for users who perform repetitive tasks. Second, function keys can be used to control hardware devices, which can be convenient for tasks such as adjusting the volume of speakers or changing the input Source on a monitor. Third, function keys can be programmed to perform specific tasks or launch specific applications, which can further increase productivity and convenience.
History
Function keys were first introduced on the IBM Model F keyboard in 1981. The original Model F keyboard had 10 function keys, labeled F1 through F10. These keys were designed to be used with the IBM Personal Computer (PC).
Over time, the number of function keys on keyboards has increased. The IBM Model M keyboard, introduced in 1984, had 12 function keys, labeled F1 through F12. The IBM Model M2 keyboard, introduced in 1987, had 15 function keys, labeled F1 through F15.
Today, most keyboards have 12 function keys, labeled F1 through F12. However, some keyboards, such as gaming keyboards, may have additional function keys that can be programmed to perform specific tasks or launch specific applications.
