Working Mechanism of Keyboard Shortcuts

Keyboard shortcuts operate by sending key event signals to the operating system or an application. When a user presses a shortcut, the OS interprets the signal and executes the corresponding command.

​
Key Event Processing

  1. Key Press Detection: When a key is pressed, the keyboard hardware sends an electrical signal to the computer.
  2. Operating System Interpretation: The OS decodes the keystroke and determines if it corresponds to a shortcut.
  3. Execution: The system or application executes the associated function.
