Lisänäppäimet

Lisänäppäimet, sometimes referred to as "bonus keys" or "extra keys" in English, is a Finnish term used to describe a set of additional keys found on certain computer keyboards. These keys are typically located in areas separate from the main alphanumeric section, often to the right of the standard QWERTY layout.

The most common form of lisänäppäimet is the numeric keypad, or numpad. This block of keys includes the digits 0 through 9, arithmetic operators (+, -, *, /), a decimal point, and an Enter key. The numpad is particularly useful for data entry tasks that involve a lot of numbers, such as accounting or spreadsheet work. It often functions as a secondary set of arrow keys and navigation keys (Home, End, Page Up, Page Down) when the Num Lock key is not active.

Beyond the numeric keypad, some keyboards might feature other specialized lisänäppäimet. These can include dedicated multimedia keys for controlling music playback (play, pause, skip), volume adjustment, or launching applications like a web browser or email client. Programmable macro keys, which can be assigned to perform sequences of actions, can also be considered a type of lisänäppäin, offering enhanced productivity for specific user workflows. The presence and arrangement of these extra keys can vary significantly between different keyboard models and manufacturers, catering to diverse user needs and preferences.
