s- is just something tagged onto the label. An example of what I use:

   exten => s,n,Dial(${ARG1},${timeOut},ron)
   exten => s,n,Noop(Initial dial failed: ${DIALSTATUS})
   exten => s,n,Goto(${DIALSTATUS})

   exten => s,n(ANSWER),Noop(Answered)
   exten => s,n,Hangup()

   exten => s,n(NOANSWER),Noop(Starting NOANSWER processing)

And so on...

the extension 's' in those lines above is the extension inside a macro.
