True, they don't. It's for the Alt-letter handling. Without it, Alt-A 
(for Address) hides the focus away somewhere & when you tab it goes 
back to the First Control Created.

It works out exactly the same, behaving fine on an EditText control, 
not on a ComboBox. 
 
Ah, I think I have another clue: when the dropdown is showing (see 
below for changes needed to that example I posted), then CR & ESC 
*are* trapped for a ComboBox; so it appears to be attaching the 
onkeyxxx to the list part rather than the edittext part of the combo?

At least you were right about something  Thanks anyway.

== update line 6 with depth 240: == 
constant name = create( ComboBox, "", MAIN, 70, 10, 200, 240, 0 ) 
= and paste these four lines in at the end to see what I mean: == 
addItem(name,"one") 
addItem(name,"two") 
addItem(name,"three") 
setText(name,"zero")
