quill-markdown-shortcuts

OP looks like it's based on Prosemirror: "A React and Prosemirror based editor that powers Outline.." FWIW: I was researching editors that supported live Markdown shortcuts (similar to Dropbox Paper) a while back, and found these alternatives to ProseMirror: HyperMD: https://laobubu.net/HyperMD -- based on CodeMirror Quill Markdown Shortcuts: https://github.com/patleeman/quill-markdown-shortcuts - plugin for Quill.js Both have their pluses and minuses. I found HyperMD to be too heavy and opted for Quill + Quill Markdown Shortcuts for my project.

FWIW, the editor they use, at least on the web, seems to be https://github.com/quilljs/quill. I'm guessing Slack implemented something a-la https://github.com/patleeman/quill-markdown-shortcuts, but not very well... In general the model of allowing separate positions for cursor inside vs outside a span is a huge improvements over WYSIWYG assigning "sticky formatting" to characters. (Hat tip to TeXmacs which was maybe first time I've met that UI pattern.) But you have to do it consistently. E.g. end of literal block has separate inside/outside but start doesn't. (Of course, in source editing, it comes for free – formatting is delimited by characters like * or ` and cursor is clearly before or after the delimeter.) ---- I believe there is a saner middle ground — formatting as syntax highlighting. You're still editing the source, no hidden
