I think you should be setting the text of the button.

So in a keyUp handler you get line 1 of the text of the control (or the
label of the control) and based on it you create your list of options. You
then set the text of the control to this list and then select the characters
as suggested. As in...

Select char length(<original label>)+1 to -1 of fld 0 of me

Based on my limited testing this works as advertised (it didn't fail on
repeated testing) on Mac OSX but I can't vouch for it on Windows.

HTH,
