Hello,

Take a peek at the /ALL_EVENTS and /EDITABLE keywords to the
WIDGET_TEXT() function. I think you want to set each of these - but you
have to communicate to the end user that a <return> or <enter> keystroke
is required. If this is the only field you are interested in polling
with the timer events, then you can actually remove the timer event (a
good thing to remove) Instead, use the event generated when the user
hits the enter key after editing your text widget.
