Enable tab completion for Markdown Snippets in VS Code

While working on a frontmatter markdown snippet in VS Code I couldn't understand why tab completion wasn't working. It turns out that some extensions (including Markdown) don't have snippet tab completion enabled by default (you can however type ctrl+Space to show available snippets with what you've typed).

VS Code has a setting for editor.tabCompletion that has 3 options: "on", "off" (default), "onlySnippets". Let's go through how to enable snippet completion for all files first and how to enable it only for a specific file type.

#Enable snippet tab completion for all extensions

Open the Command Pallete (⌘+shift+p in MacOS, ctrl+shift+p in Windows)cmd-p, type "Open Settings (JSON)" and press return. This will open the file settings.json.

At the bottom of the file, add the following (don't forget to add a comma to the item before! Otherwise you'll get a syntax error):

"editor.tabCompletion": "onlySnippets"

Save your User Setttings configuration, open a Markdown file and type FM

Markdown Snippet Tab Completion

  1. If you have your settings to default to Open Settings (JSON), you can use ⌘+, in MacOS, ctrl+, in Windows.
