;
#X text 61 87 you might see this ->;

#X text 270 86 and ask:;
#X text 59 120 - If this is not a symbol \, what the hell is it???
;
#X text 50 164 You might even remember we used it before to stop the
[metro] \, like here:;
#X text 56 460 The thing is that some objects were designed to work
with atomic symbol messages that are not symbol messages! These are
better thought of as "commands".;

;
#X msg 133 727 open 14.wav;
#X text 56 670 We'll see later on how these comands don't need to be
just an atom \, we can have a message like:;
#X text 50 948 ============================================================
;
#X text 53 384 Selectors are always the first atom on a message \,
no matter if it is a one element message or not. So you can still think
of these messages as messages having other types of "selectors".;
#X text 56 763 This is not a list \, but can be used to open a soundfile
called "14.wav"! If you send that message to an object that is not
design to respond to that \, it will check the selector and interpret
"open" as its data type.;
