If it serves no funaction then it should not be there; in my book.

This is another thing entirely, unrelated to key presses and functionality.

Control characters that serve no purpose and are obsolete maybe should 
either be ignored, filtered out, or flagged.

A good text editor should have a mode or option to allow showing control 
characters. Maybe at somepoint Squeaks editor may get this functionality but 
it is not really a pressing issue.

The <shift><insert> charcter bug should be reported by someone, if it has 
not been already.
