Right now the “toggle comment” shortcut only adds %%%% style comments, which are incompatible with most other markdown editors I’m aware of, and are not compatible with the markdown processor I’m using to generate html for my website.
It would be very useful to have an option to use the standard HTML-style comments instead.
Having a shortcut for that would make a big difference, because when you need to use comments often (as I do), typing them every time is a pain in the ass.
