71. Keyboard - Event Handling
The KeyPress event occurs when the user presses a key that represents an ASCII character
The specific key can be determined with property KeyChar of the event handler's KeyPressEventArgs argument
The KeyPress event does not indicate whether modifier keys (e.g., Shift, Alt and Ctrl) were pressed when a key event occurred
If this information is important, the KeyUp or KeyDown events can be used
The KeyEventArgs argument for each of these events contains information about modifier keys
