Your model can supply a selector that will be used to set the selection.

It should return an Interval.

Look at PluggableTextMorph class>>
	on: anObject text: getTextSel accept: setTextSel readSelection: 
getSelectionSel menu: getMenuSel

it's the getSelectionSel argument to this method.

Having set this (let's say to #contentsSelection), if your model then says:

	self changed: #contentsSelection

the PTM will ask your model for the proper selection interval.

You can also force the selection interval by calling #selectionInterval:

Yes, you can look at the selection interval (there is a selectionInterval 
instance variable in PluggableTextMorph but for some reason there is no 
accessor for it).
