Sorry for the top posting... I noticed Nils had this function defined in
denemo-modules/selection.scm
SingleAndTaggedSelectionSwitcher this applies to the single object or all
objects under selection.

So in the file AccentSelectionSwitcher he has:
(SingleAndSelectionSwitcher d-ToggleAccent)

This applies to every note in the selection. I think d-ToggleAccent is a
built-in though. I am sure it can be replaced. Is this what the menu items
should contain (of course replace d-ToggleAccent with the new scripts
procedures?). The script procedure would probably best be defined in the same
file perhaps.

I am not sure how the denemo-modules work. In my local git (I have not pushed
it yet), I created a file denemo-modules/fonts.scm. It contins:
;;; Emmentaler rests
(define REST0 "")
(define REST1 "")

(define REST2 "")
(define REST3 "")
(define REST4 "")
(define REST5 "")
(define REST6 "")
(define REST7 "")

(define Rest0  (string-append "\n" REST0 "\nemmentaler"))
............

I cut these out of denemo.scm. Is this correct. Do these modules get sourced on
startup or do they have to be specifically loaded like this:

OK, I have checked in d-Marcato
I think it could be improved before we start cloning it for every sort
of articulation (and indeed all the other sorts of marks, both
stem-direction sensitive and not, ie DENEMO_ALT_OVERRIDE and not)
One thing is to test Marcato::params which is set #f unless called from
a script - this way a script can force Marcato rather than just toggle
it.
And the body of this example could be a utility function placed
somewhere in denemo-modules - perhaps Nils already has this done?

Any other improvements????

NOTE: there is a long-standing bug with the display not expanding when
you add things too high to be seen. So applying d-Marcato to the top
staff on a stem-down note will result in the marcato being off screen at
the top. Time to fix this.
