well, not exactly...
here's the thing : I have a hidden option button with several choices :
  choice1
  choice2
  choice2

At some point the content of the btn gets updated and it becomes visible
with the following script :
  put "choice4" & return & "choice5" & return & "choice6" into btn 1
  set label of btn 1 to line 2 of btn 1
  set menuhistory of btn 1 to 2

The purpose of the "menuhistory" line is, when user press the btn,
to have all the choices "centered around" the visible one on the label,
which is more elegant imho...
