I also failed to make Vim plugin work. From CodeMirror official site <https://codemirror.net/demo/vim.html>
Note: The CodeMirror *vim bindings do not have an active maintainer.* That means that if you report bugs in it, they are likely to go unanswered. It also means that if you want to help, you are very welcome to look at the open issues and see which ones you can solve. But still, it could be an error in TiddlyWiki. Nonetheless, for the time being, I have switched to Wasavi <http://appsweets.net/wasavi/> addon on to get Vim inside TiddlyWiki editor. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
