Key rollover is the ability of a computer keyboard to correctly handle several simultaneous keystrokes. A keyboard with n-key rollover (NKRO) can correctly detect input from each key on the keyboard at the same time, regardless of how many other keys are also being pressed. Keyboards that lack full rollover will register an incorrect keystroke ...
In computing, a keyboard shortcut is a sequence or combination of keystrokes on a computer keyboard which invokes commands in software. Most keyboard shortcuts require the user to press a single key or a sequence of keys one after the other.
WhatPulse is a key-counting program that monitors computer uptime, bandwidth usage and the number of keystrokes and mouse clicks made by a user over a period of time. Unlike keyloggers, the authors claim WhatPulse does not record the order in which keys are pressed but instead counts the number of times keys are pressed. [2]
Keystroke dynamics, or typing dynamics, is the obtaining of detailed timing information that describes exactly when each key was pressed and when it was released as a person is typing at a computer keyboard for biometric identification, [32] similar to speaker recognition. [33] Data needed to analyze keystroke dynamics is obtained by keystroke ...
The keyboard switch matrix is wired to its inputs and it processes the incoming keystrokes and sends the results down a serial cable (the keyboard cord) to a receiver in the main computer box. It also controls the illumination of the " caps lock ", " num lock " and " scroll lock " lights.

A keystroke sequence like STO 4 2 (store the currently-displayed number into memory 42) would be encoded as 42 42. In this case the first 42 is the key code for the STO key, but the second 42 is not a key code, but a memory register number.
Therefore this was the scheme used by the earliest DOS games. The numpad or number pad keys are used quite often, but are used mostly in driving simulator games. This is mainly because these games usually have quite a large number of keys needed to control the vehicle properly and the number pad will have plenty of keys for that particular use.
