Didier Verna writes: Oh yeah, I forgot to mention that I tried doing that, and it didn't work either. I also read the font-lock.el and concluded that it was saying that <mode-name>-font-lcok-keywords was the most authoritative setting. Can anyone explain to me what has changed in the font lock code that would cause configuration settings that worked in 19.11->20.4 to fail in 21.0? I can't really tell if I'm doing something wrong, or if other beta testers are just not generally in the habit of overiding the default colorization settings. I agree the situation seems confusing to me. I would like to have a clear understanding of how to customize font-lock-keywords on a per mode basis. I thought I had that in the XEmacsen before 21, but with 21 my old code doesn't work, and my attempts to do what the comments say, is also not working. Any additional advice appreciated. -- Geoffrey Furnish Actel Corporation furnish(a)actel.com Senior Staff Engineer 955 East Arques Ave voice: 408-522-7528 Placement & Routing Sunnyvale, CA 94086-4533 fax: 408-328-2303
