The way I did something like this is to lock the field. When you click
on the field, a mousedown/up script can be run that uses the clickloc,
the field's rect, and the field's scroll to calculate the line in the field.
Alternatively, you can unlock the field, click on the leftedge,yloc and
shiftclick on rightedge,yloc to select the entire line, and then use the
selection to do further processing (don't forget to relock the field).
