Org-transclusion lets you insert a copy of text content via a file link or ID link within an Org file. It lets you have the same content present in different buffers at the same time without copy-and-pasting it. Edit the source of the content, and you can refresh the transcluded copies to the up-to-date state. Org-transclusion keeps your files clear of the transcluded copies, leaving only the links to the original content.

Font Lock Studio is an interactive debugger for Emacs syntax highlighting rules, also called Font Lock keywords. It can single-step Font Lock keywords -- matchers, highlights, and anchored rules, to see what happens when a buffer is fontified. Breakpoints can be set on or inside rules. When inside a rule, matches are visualized using a palette of background colors. The explainer can describe a rule in plain-text English. Finally, tight integration with Edebug allows stepping into Lisp expressions that are part of the Font Lock keywords.
