Emacs: persistent highlighting of a region

Question

The Emacs extension markerpen.el (link text) allows you to hightlight arbitrary regions in your buffer. With this extension, the added highlighting is lost once you kill the buffer though. However, it would be nice to be able to highlight arbitrary regions of a file in a "persistent" way -- in the sense that the added hightlighting is not lost after I close the file.

Do you know of any way I could have such a "persistent" highlighting?

Thanks very much.

Answer 1

Try enriched-mode.

Answer 2

Yes, such a feature does exist. And you can add the highlighting in any number of ways, including sweeping the mouse marker pen-style.
