Two good points. So why do we need \pointAndClickOn?
John Mandereau (whom I've just met with) has just given me an example
of a case where one would need a \pointAndClickOn:
suppose you have a default stylesheet file, called e.g. "layout.ly",
that you use in all your scores, and which disables point-and-click;
suppose you temporary want to re-enable point-and-click in your
"master" file, but without modifying your layout file. Then:
%%%
\include "layout.ly"
\pointAndClickOn
%%%
... is your friend.
