Hi all, probably an easy question: for a presentation, I would like to have an area of my slide highlighted by placing a transparent grey layer on top of the slide and having one area of this layer completely transparent, a bit like this screenshot: http://debaday.debian.net/wp-content/uploads/2007/05/key3.jpg Any suggestions for the easiest way to achieve this effect? Thanks Thomas
