numeronäppäimistö

Numeronäppäimistö, often referred to as the numeric keypad or numpad, is a dedicated section of a computer keyboard that provides a calculator-style arrangement of numeric keys, arithmetic operators, and function keys. Typically located on the right-hand side of a standard QWERTY keyboard layout, it simplifies and speeds up data entry, especially for numerical information.

The keys on a numeronäppäimistö usually include the digits 0 through 9, a decimal point, and basic arithmetic operators such as addition (+), subtraction (-), multiplication (*), and division (/). It also often features an Enter key and a Num Lock key. The Num Lock key serves as a toggle; when activated, the keys function as numbers. When deactivated, they typically revert to their secondary functions, which can include arrow keys, Home, End, Page Up, and Page Down.

Numeronäppäimistö is particularly beneficial for tasks involving frequent numerical input, such as accounting, data analysis, programming, and using spreadsheet software. Its layout is designed for efficient thumb and finger operation, allowing users to input numbers without needing to shift their hands to the top row of the keyboard. For users who primarily work with numbers, a dedicated external numeronäppäimistö can further enhance productivity.
