Yes, I find that the first time you type $ there is no snippet.

I found that after typing "$",
Maybe there are some conflicts between the build-in tabCompletion setting with "Markdown All in One".
Anyway, the "ctrl + space" solution work for me very well.
Thank you for sharing such a great VS extension. 👍
Quick suggestion is disabled on Markdown by default. To get your behavior without the need for ctrl + space, add this to your User Settings:
"[markdown]": {
"editor.wordWrap": "on",
"editor.quickSuggestions": true
},
The editor.tabCompletion:true actually does not behave like I'd expect regardless if editor.quickSuggestions is true or false. I am not sure why tabCompletion without quickSuggestion won't work
@ketozhang tab key is overridden for the usage of indenting list
@neilsustc Shouldn't that tab only refer to listing environment such that:
# snippet tabCompletion is active here but not listing tab
* Item 1
* Item 1a #listing tab is active here but not tabCompletion
tabCompletion will work with v0.11.2!
