I write a lot of Markdown and use the linebreak syntax a lot. Here is an example of the highlighting in Emacs.
Unfortunately, I haven’t figured it out to get it in Sublime Text. Does somebody know a Markdown syntax package that supports that and a corresponding colour scheme?
Personally, I use and prefer Monokai Pro and @monokai says on the corresponding github issue that he would need a Markdown syntax definition that supports that scope and than can he highlight it with his colour scheme.
