So far, this discussion seems to assume that we would be concerned by
_changes_ in field content.  But I can easily think of applications for
a function that would sense a word click _before_ any change has
occurred.  For example, you might want to allow a user to change field
contents, but may want to warn him; or give him some explanation regarding
the nature of the permissible changes.  We can always go around the limitations
(with a help button, be copying the initial content and asking to confirm
eventual changes if a closeFiled message is sent, etc...) but it could be
simpler.  Stephane
