Menu2input delegate

Hello, 

I would like to capture key up and key down events while using the menu2 system. 
In looking at the documentation and examples I see methods for onBack, onDone, and onSelect

WatchUi.Menu2InputDelegate

The new Menu2InputDelegate class is used to handle selected Menu2 items. This object handles these selections with three methods:

• onBack() - Handles the back key and pops the current page off the stack if not overridden.
• onDone() - Used with a specialized CheckboxMenu. Pops the current page when not overridden.
• onSelect() - Handles when a Menu2 item is selected.

For more, see the Menu2Sample sample app distributed with the SDK.

Is there anyway to access keyup and keydown events using menu 2 ? 

Thank you.
