[Squeakland] [Q] E-Toy: How to hook a button to other object

  There are a quite a few different ways.

  #1:
   * For the "Button" from the supplies bin, get the halo for it.
   * There is a pale green/blue handle near the bottom right corner.
   * You'll get the scriptor that is invoked when you click it.  (You
     can programatically invoke the button's action by sending "fire"
     command in the "button" viewer category.

  #2:
   * For any object, you can make it a button.
   * Create a scriptor for an Etoys object.
   * Hold the mouse button for a second on the "script status" that is
     showing "Normal" by default.  You'll get a menu.
   * From the menu, choose "mouseDown" or "mouseUp".  The script will
     be executed when you do click on (or click on and release) the
     object.
