See full key binding list in the keyboard shortcuts section

• Run command "Create Table of Contents" (in the VS Code Command Palette) to insert a new table of contents.

• The TOC is automatically updated on file save by default. To disable, please change the toc.updateOnSave option.

• The indentation type (tab or spaces) of TOC can be configured per file. Find the setting in the right bottom corner of VS Code's status bar.

  Note: Be sure to also check the list.indentationSize option.

• To make TOC compatible with GitHub or GitLab, set option slugifyMode accordingly

• Three ways to control which headings are present in the TOC:

  Click to expand

  1. Add <!-- omit from toc --> at the end of a heading to ignore it in TOC
     (It can also be placed above a heading)

  2. Use toc.levels setting.

  3. You can also use the toc.omittedFromToc setting to omit some headings (and their subheadings) from TOC:

     // In your settings.json
     "markdown.extension.toc.omittedFromToc": {
       // Use a path relative to your workspace.
       "README.md": [
           "# Introduction",
           "## Also omitted",
       ],
       // Or an absolute path for standalone files.
       "/home/foo/Documents/todo-list.md": [
         "## Shame list (I'll never do these)",
       ]
     }

     Note:

     • Setext headings (underlined with === or ---) can also be omitted, just put their # and ## versions in the setting, respectively.
     • When omitting heading, make sure headings within a document are unique. Duplicate headings may lead to unpredictable behavior.

• Easily add/update/remove section numbering

  

• In case you are seeing unexpected TOC recognition, you can add a <!-- no toc --> comment above the list.

Note: By default, this extension tries to determine indentation size for different lists according to CommonMark Spec. If you prefer to use a fixed tab size, please change the list.indentationSize setting.

• Commands Markdown: Print current document to HTML and Markdown: Print documents to HTML (batch mode)

• Compatible with other installed Markdown plugins (e.g. Markdown Footnotes). The exported HTML should look the same as inside VS Code (except for a few theme colors due to the limitations of APIs).

• Use comment <!-- title: Your Title --> (in the first line) to specify a title of the exported HTML.

• Plain links to .md files will be converted to .html.

• It's recommended to print the exported HTML to PDF with browser (e.g. Chrome) if you want to share your documents with others.

• Table formatter

  

  Note: The key binding is Ctrl + Shift + I on Linux. See Visual Studio Code Key Bindings.

• Task lists

Please use Markdown+Math for dedicated math support. Be sure to disable math.enabled option of this extension.

Tip: also support the option completion.root

• Images/Files (respects option search.exclude)

  

• Math functions (including option katex.macros)

  

• Reference links

  

• Paste link on selected text

  

• Add "Close Preview" keybinding, which allows you to close the preview tab using the same keybinding of "Open Preview" (Ctrl + Shift + V or Ctrl + K V).

• Markdown All in One: Create Table of Contents
• Markdown All in One: Update Table of Contents
• Markdown All in One: Add/Update section numbers
• Markdown All in One: Remove section numbers
• Markdown All in One: Toggle code span
• Markdown All in One: Toggle code block
• Markdown All in One: Print current document to HTML
• Markdown All in One: Print documents to HTML
• Markdown All in One: Toggle math environment
• Markdown All in One: Toggle list
  • It will cycle through list markers (by default -, *, +, 1. and 1), which can be changed with option list.toggle.candidate-markers).

• In most cases, it is because VS Code needs a few seconds to load this extension when you open a Markdown file for the first time. (You will see a message "Activating Extensions..." on the status bar.)

• If you still see this "command not found" error after waiting for a long time, please try to restart VS Code. If needed, reinstall this extension:

  1. Uninstall this extension.
  2. Close and restart VS Code. (important!)
  3. Reinstall this extension.

• If it doesn't help, feel free to open a new issue on GitHub. It would be better if you can report any suspicious error information to us: It's usually in VS Code's menubar Help > Toggle Developer Tools > Console.

• (As a last resort, you may choose to delete onXXXKey keys through VS Code's Keyboard Shortcuts editor if you do not need the list editing feature at all.)

• CommonMark
• Tables, strikethrough and task lists (from GitHub Flavored Markdown)
• Math support (from KaTeX)
• Front matter

For other Markdown syntax, you need to install the corresponding extensions from VS Code marketplace (e.g. Mermaid diagram, emoji, footnotes and superscript). Once installed, they will take effect in VS Code and also the exported HTML file.

You can easily manage key bindings with VS Code's Keyboard Shortcuts editor. (Commands provided by this extension have prefix markdown.extension.)

From experience, there is a good chance that the performance issues are caused by other extensions (e.g., some spell checker extensions).

This can be verified if you try again with all other extensions disabled (execute Developer: Reload with Extensions Disabled or Extensions: Disable All Installed Extensions for this Workspace in the VS Code command Palette) and then enable this extension.

To find out the root cause, you can install our development build (debug.vsix) and create a CPU profile following this official instruction from the VS Code. And then please open a GitHub issue with that profile (.cpuprofile.txt) attached.

See CHANGELOG for more information.

Download it here, please click the latest passing event to download artifacts.

There are two versions: markdown-all-in-one-*.vsix is the regular build, while debug.vsix is used to create a verbose CPU profile.

To install, execute Extensions: Install from VSIX... in the VS Code Command Palette (ctrl + shift + p)
