For adding a new button called BBB, you need to
  1. add a halospec for addBBBHandle to Preferences class (see senders of 
addScriptorHandle: for the list)
  2. add wantsBBBHaloHandle to Morph (returning false)
  3. add method addBBBHandle to HaloMorph (see addScriptorHandle: for an 
example).
  4. Add wantsBBBHaloHandle method (returning true) and a event handler to 
your Morph

See senders and implementors of addScriptorHandle: for an example.
