As many of us have experienced, columnar output doesn't line up very well if the font is something like New York. This means that a selection out in the white space at the end of lines has an indeterminate value. Since tab marks on this kind of editor are pixel based rather than column based, they also pose problems with this sort of selection. Only with the assumption of fixed width fonts do 'rectangular' selections become easy to implement and use. Kurt
