I'm not sure I understand the objection here. The form suggested by Drew just gets a list of font names -- it doesn't load anything, so it should be harmless? And the doc string of describe-font seems to be wrong. You can ask it to describe a font that's not loaded. Or at least it seems that way when I test it. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
