Grid Editing and Range Selection

I have a String Grid which I would like to be able to allow users to
type in and edit text as well as select (via the mouse) a range of cells
for copying to other apps.  Delphi (1 & 3) does not allow editing and
range selection.  If you turn on the option goEditing then you can edit
but not select a range of cells using the mouse (you can using the
cursor keys).  If you have goRangeSelect then goEditing has to be off to
allow the range selection.

Any suggestions?
