Handling Mouse-down and Key-down Messages

When the user of the control begins interacting with it, the control receives either mouse-down messages (WM_LBUTTONDOWN, WM_MBUTTONDOWN, or WM_RBUTTONDOWN) or a key-down message (WM_KEYDOWN) from Windows. To enable a control to respond to these messages, you must write handlers that respond to these messages.

- Responding to mouse-down messages.
- Responding to key-down messages.
