This and camel case links make use of the $link widget, so modifying it can modify the behaviour you ask. As I said I have a working example of this that adds content before or after such links when detected.
- Modifying core tiddlers is not recommended, but overriding them with the new features possibly the next best thing, unless we want the change to become part of TiddlyWiki.
I have just spent more than an hour dealing with some erratic behaviour in FireFox after working with this, so I need to proceed with caution.
- See this Topic I stareted before 5.3.0 release Exploring default tiddler links hackability in V5.3.0
- am looking to see if I can address your requirement in the code I have, but I am not fully informed yet.
