We are using FEB 8.6.2. Our customers prefer hitting Enter key to navigate to next field. I tried to use dojo.connect to connect Enter key, but it's to no avail. Communicating with Chris Dawes from IBM and I learned that FEB has not exposed the keypress events (onkeydown or onkeyup) and therefore there is no way to detect and react to the "Enter" key.
Hope the new release of FEB will expose those key events.
