That is easy - load the score then move the cursor to each CHORD and
execute the directive put commands - I think Nils may have a one-liner
to apply a given procedure to every chord in a movement. My recent
scripts (e.g. fix slurs called by CheckScore) do this sort of traversal
of a score.

accidentals are ok, it just hides the chord.

yes - see above - you would create a procedure to be executed on each
CHORD, as I say Nils probably has one, perhaps also with a test
procedure (ie for-each-object-in-score test dothunk) which does dothunk
if test is true until there are no more objects, and then returns to the
original position.
