- moved more common editing code from field-type specific functions into
wrappers - editable fields can now be traversed with Tab - Enter commits all editable fields - Esc resets all editable fields to their initial content git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5402 99fdad57-331a-0410-800a-d7fa5415bdb3
