Bob Philips provided the code below in answer to someone's question. It
highlights the line of the active cell. This is SO useful to my team, that I
want to be able to add it to any worksheet we use.

1. Is there a way to make a macro that adds code (the code below) to the
active worksheet? (I would then make an addin for the group that copies in
the below)

2. If not, can the below be applied easily to every sheet in a workbook?

3. If I wanted this to be part of the default workbook (Excel XP), how
would I do this? Would it then be present on every sheet added?

Daniel
(PS, thanks Bob)
