Hans, I have the following sample: \starttext \startTEXpage[offset=1em] \startTEX This is text. % and this is a comment \stopTEX \startXML <p>This is text.<!--and this is a comment--></p> \stopXML \startLUA if code=="code" then --this is a comment --[[ and this is a multiline comment --]] \stopLUA \stopTEXpage \stoptext All comments are colored in darkyellow, but the issue is that in Lua and TeX only the comment markers are colored, while in XML only the comment content is colored. Because it is basic to display what it won’t affect to the interpretation or compilation of the code, would it be possible that the whole comments (both markers and content) could be colored? Sorry, but in all the code editors I have used in my life, comment coloring involved both markers (or delimiters) and content. Many thanks for your help, Pablo -- http://www.ousia.tk
