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.
Keyboard shortcuts are generally used to expedite common operations by reducing input sequences to a few keystrokes, hence the term "shortcut". [12] To differentiate from general keyboard input, most keyboard shortcuts require the user to press and hold several keys simultaneously or a sequence of keys one after the other.
Theoretically the number of keystrokes required per desired character in the finished writing is, on average, comparable to using a keyboard. This is approximately true providing that all words used are in its database, punctuation is ignored, and no input mistakes are made typing or spelling. [1]
A gaming keypad is a small, auxiliary keyboard designed only for gaming. It has a limited number of the original keys from a standard keyboard, and they are arranged in a more ergonomic fashion to facilitate quick and efficient gaming key presses. The commonly used keys for gaming on a computer are the 'W', 'A', 'S', 'D', and the keys close and ...
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 ...
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]
The original purpose of word prediction software was to help people with physical disabilities increase their typing speed, [2] as well as to help them decrease the number of keystrokes needed in order to complete a word or a sentence. [3]
