How do we prevent the 'marching ants' on a clipboard copy?

when highlighting cells followed by a copy, the cells are surrounded by the ‘marching ants’ outline. How do we prevent the this? I already know ESC will clear them - I don’t want them to show in the first place.

I want to know the same thing. They are soo-o-o-o annoying – just like Excel. Don’t have to put up with them with OpenOffice.
