I am off once again teaching an XML class using oXygen. When we do this, we often project an XML document up on the screen and select an area (typically an element with some children) as being that to which we want the students to pay attention. But as soon as we've selected it in order to highlight it, the background becomes distinctive (gray in my case, but can be changed in the preferences), and color syntaxing is lost. I'd like to somehow have the reverse visual effect. I'd like everything else to be gray and dull w/o syntax highlighting, and the selected text to be bright and with syntax highlighting. Of course, I don't want the whole file to be w/o syntax highlighting until I select something. I want the act of selection to make everything else look dull, leaving the selection bright and cheery. One way to achieve this would be to have a "inverse selection" command. I realize that doing so would mean that there would be two discontiguous chunks of selection, and I'm not sure that's easy to do, or a good idea. But *some* way to achieve this marvelous pedagogical goal would be appreciated.
