editing cell contents without having to double click cell
<< But it seems Excel forces one to
always double click the cell. I want rapid entry without having to
rely on the mouse to position the insertion point. >>
I'm sorry but your wrong.
On a windows version of Excel You just press the [F2] key and that will
activate the cell and put the insertion point at the end of the text.
On a Mac it's [Command] + [U] (that's the Mac key and the U key).
