I don't mean a default value - I mean pre-selected as in "in region". e.g when you tab to a field in a web form for example - The data in the field is highlighted/selected. I already had a default value set as "url" in the code above. e.g goto www.Google.com enter some text and tab to a button then tab back. The text in the search field is selected. -- important and urgent problems of the technology of today are no longer the satisfactions of the primary needs or of archetypal wishes, but the reparation of the evils and damages by the technology of yesterday. ~Dennis Gabor, Innovations: Scientific, Technological and Social, 1970
