Well, here is a sample script that does that - better it allows you to
enter two punctae and then hit flexa and it does the selection of the
two notes for you.


(let ((tag "Flexa"))
(if (and (not (d-HasSelection)) (d-PrevChord))
        (begin
                (d-SetMark)
                (d-NextChord)
                (d-SetPoint)))
        
(if (MoveToSelectionBeginningInThisStaff)
        (begin
                (d-DirectivePut-chord-prefix tag "\\[ ")
                (d-DirectivePut-chord-postfix tag "\\flexa ")
                (d-DirectivePut-chord-display tag "fl--")
                (d-DirectivePut-chord-override tag 16)
                (if (d-NextChord)
                        (begin
                        
                                (d-DirectivePut-chord-postfix tag "\\]  ")
                                (d-DirectivePut-chord-display tag "--]")
                                (d-DirectivePut-chord-override tag 16)))
                                (d-MoveCursorRight)
                (d-SetSaved #f))
        (d-WarningDialog (_ "You must select two notes"))))
