erikoisnäppäin

Erikoisnäppäin, often translated as "special key" or "function key," refers to a key on a computer keyboard that does not produce a standard character when pressed. Instead, these keys are designed to perform specific commands or actions within a software application or the operating system itself.

Common examples of erikoisnäppäin include keys like F1 through F12, which are frequently used for functions such as accessing help (F1), saving files (often Ctrl+S, but F12 can also be used for saving), or refreshing a web page (F5). Other special keys include the arrow keys, Home, End, Page Up, Page Down, Delete, Insert, and the modifier keys like Shift, Ctrl, Alt, and the Windows key (or Command key on macOS).

The functionality of an erikoisnäppäin is context-dependent. For instance, the same key might perform a different action depending on which application is currently active. Programmers and power users often utilize these keys in combination with others (keyboard shortcuts) to streamline their workflow and increase efficiency. The precise layout and available special keys can vary slightly between different keyboard models and operating systems.
