Don't we have tests for numbers and rectangles? Do they pass?

A quick look at the selection mechanism in lists revealed these calls:
PluggableListMorph >> #rowAtLocation: (with a coordinate transformation)
LazyListMorph >> #rowAtLocation: (with calls to #min: #min:max: etc.)

You could write event positions to the transcript.
