Basically you look for the Return character in your event
handler, and use the /INPUT_FOCUS keyword to WIDGET_CONTROL()
to give the next text widget input focus:

In your event handler:

"WIDGET_TEXT_CH":
WIDGET_CONTROL, event.id, get_value=text
state.text = text ; Store the text somewhere
if ( event.ch eq 10B ) then begin
WIDGET_CONTROL, next_text_widget, /input_focus, get_value=txt
WIDGET_CONTROL, next_text_widget, $
set_text_select=[strlen(txt(0)), 0]
endif else begin
....
endelse
end

I've mailed you a short routine called GET_TEXT.PRO that brings
up a popup widget and allows you to enter text in one or more
text widgets. It's pretty easy to use, and it will show you in
more detail how to do this. If anyone else is interested in
this, let me know.
