 ## Hotkeys
 
 Hotkeys are added with `KeyboardListener`. A KeyboardListener can be added to a Node, and will fire its callback
-whenever the specified keys are pressed while the Node has focus. Here is an example:
+whenever the specified keys are pressed while the Node has focus. The keys should be defined with HotkeyData.
+Create a public static field in your class that is an instance of HotkeyData. Use the HotkeyData in your keyboard
+listener and in your keyboard help dialog so that commands and labels are defined in one place. HotkeyData also
+supports auto-generated documentation for hotkeys.

 ```ts

-Be careful not to add hotkeys that collide with other global hotkeys defined by PhET such as hotkeys that pan and zoom
