Markdown Support for Visual Studio Code
All you need for Markdown (keyboard shortcuts, table of contents, auto preview and more).
Note: VS Code has basic Markdown support out-of-the-box (e.g, Markdown preview), please see the official documentation for more information.
Table of Contents
Features
Keyboard shortcuts
(Typo: multiple words)
See full key binding list in the keyboard shortcuts section
Table of contents
-
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 `` 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:
```js
// 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.
List editing
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.
Print Markdown to HTML
-
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.
GitHub Flavored Markdown
Math
Please use Markdown+Math for dedicated math support. Be sure to disable math.enabled
option of this extension.
Auto completions
Tip: also support the option completion.root
Others
-
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).

FAQ
Q: Error "command 'markdown.extension.onXXXKey' not found"
-
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:
- Uninstall this extension.
- Close and restart VS Code. (important!)
- 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.)
Q: Which Markdown syntax is supported?
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.
Q: This extension has overridden some of my key bindings (e.g. Ctrl + B, Alt + C)
You can easily manage key bindings with VS Code's Keyboard Shortcuts editor. (Commands provided by this extension have prefix markdown.extension
.)
Q: The extension is unresponsive, causing lag etc. (performance issues)
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.
Changelog
See CHANGELOG for more information.
Latest Development Build
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
)
