Virtual Key codes provide a symbolic representation of user key presses.

Virtual key codes allow you to represent keyboard values for non-alphanumeric keys. Windows defines special constants for each key the user can press. These constants can then be used to refer to the keystroke in Windows API calls or in an OnKeyUp or OnKeyDown event handler. Most of the virtual key codes are defined in the Windows unit.

The following table lists the virtual key codes defined in the Windows unit:
