What Is The Num Lock Key And What Is Its Purpose?
The Num Lock key is a toggle key found on most computer keyboards, typically located in the top left corner of the numeric keypad. Its primary function is to switch the numeric keypad between two modes: numeric input and navigation. When Num Lock is enabled, the numeric keypad enters numeric input mode, allowing users to enter numbers and mathematical symbols.
In this mode, the keys on the numeric keypad function as expected, with the number keys producing numbers and the mathematical operator keys producing their respective symbols. This mode is useful for tasks such as data entry, calculations, and gaming. When Num Lock is disabled, the numeric keypad enters navigation mode, where the keys function as arrow keys and other navigation controls.
Where Did The Num Lock Key Originate From?
The Num Lock key originated from the early days of personal computers, specifically from the IBM PC keyboard layout introduced in the 1980s. At that time, keyboards did not have a separate set of navigation keys, and the numeric keypad was used for both numeric input and navigation. The Num Lock key was introduced as a way to toggle between these two modes, allowing users to switch between entering numbers and navigating the screen.
The Num Lock key was initially designed to be a convenience feature, allowing users to quickly switch between modes without having to press multiple keys. Over time, the Num Lock key has become a standard feature on most computer keyboards, and its function has remained largely unchanged.
Why Is The Num Lock Key Still Present On Modern Keyboards?
Despite the widespread use of separate navigation keys on modern keyboards, the Num Lock key remains a standard feature on most keyboards.
