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.

Cape provides some Completion At Point Extensions, which can be used in combination with Corfu completion UI or the default completion UI.

All values are customizable.
