263 A common example of an encoder is a device with a turning knob that tells the hosting
266 With an encoder your application can receive events from the following:
275 - By turning the encoder you can focus on the next/previous object.
276 - When you press the encoder on a simple object (like a button), it will be clicked.
277 - If you press the encoder on a complex object (like a list, message box, etc.)
