Hi Ken,
Escape and Enter are a platform convention for closing a sheet or dialog, so
overriding their behavior may not be a good idea.
However-

This actually doesn't work. Consuming an event simply stops its propagation up
the component hierarchy. It doesn't prevent other listeners on the same
component from receiving the event.

This will work. You don't actually need to create a custom sheet class for this
- you can simply replace the mapping for the standard Sheet class in the theme.
Another option is to attach a SheetStateListener to the sheet. You can return
Vote.DENY from previewSheetClose() to prevent the sheet from closing (perhaps
based on the state of some property that you would set when your custom close
button is pressed).
