A boss key, or boss button, [1] is a special keyboard shortcut used in PC games or other programs to hide the program quickly, possibly displaying a special screen that appears to be a normal productivity program (such as a spreadsheet application).
Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, [1] [2] typically covertly, so that a person using the keyboard is unaware that their actions are being monitored.
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.
Hardware keyloggers are used for keystroke logging, a method of capturing and recording computer users' keystrokes, including sensitive passwords. [1] They can be implemented via BIOS-level firmware, or alternatively, via a device plugged inline between a computer keyboard and a computer. They log all keyboard activity to their internal memory.
In full-duplex systems, keystrokes are transmitted one by one. As the main computer receives each keystroke, it ordinarily appends the character which it represents to the end of the keyboard buffer. The exception is control characters, such as "delete" or "backspace" which correct typing mistakes by deleting the character at the end of the buffer.
Composite of two Macintosh Finder menus with keyboard shortcuts specified in the right column In computing , a keyboard shortcut (also hotkey / hot key or key binding ) [ 1 ] is a software -based assignment of an action to one or more keys on a computer keyboard.
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 ...
Although it happens on a scale too small to be visible to the naked eye, it can be enough to register multiple keystrokes. To resolve this, the processor in a keyboard debounces the keystrokes, by averaging the signal over time to produce one "confirmed" keystroke that (usually) corresponds to a single press or release. Early membrane keyboards ...
