Num Lock
Calculator mode activator
Num Lock is a toggle key on computer keyboards that switches the numeric keypad between number entry and navigation functions.
When Num Lock is on, the keypad types digits; when off, those keys control cursor movement and other functions.
I accidentally turned off Num Lock and couldn't type numbers.
