Syntax highlighting

Font Options

GitHub and other flavors

Advanced markdown extensions are supported to give more features to the syntax. This includes pipe tables, emoji, mathematics and a lot more.

Live Preview Window

The preview window opens up on the right side of the document when it opens.

Preview window

Every time the markdown document is modified, the preview window will update.

Any code blocks receives full syntax highlighting in the preview window. Here's an example of JavaScript code rendered.

Code Colorizing

The preview window is automatically scrolled to match the scroll position of the document. As the document is scrolled up and down, the preview window will follow.

Live preview can be disabled in the settings.

The syntax highlighter is powered by Prism

Custom stylesheets

The preview window supports loading of custom stylesheets. It will look for a file called md-styles.css in the same directory as the currently opened markdown file or any parent directory.

If no md-styles.css file is found it will look for it in %userprofile%. If it still isn't found it will use the built in stylesheet.

To generate a custom stylesheet, simply right-click inside the markdown editor document and select Add Custom Stylesheet...

Custom Stylesheet

The name of the custom stylesheet can be changed in the settings.

Preview HTML template

The preview window also supports loading of HTML template, which will be detailed in Auto-generate HTML files section.

When the markdown document is updated, the markdown editor will call onMarkdownUpdate function if it exists. With this feature, you can support your own scripts, for example KaTeX for LaTeX.

Drag 'n drop images

Drag an image directly from Solution Explorer onto the document to insert the appropriate markdown that will render the image.

Paste images

This is really helpful for copying images from a browser or for inserting screen shots. Simply copy an image into the clipboard and paste it directly into the document. This will prompt you for a file name relative to the document and then it inserts the appropriate markdown.

It will even parse the file name and make a friendly name to use for the alt text.


Any fenced code and HTML blocks can be collapsed, so that this:

Outlining Expanded

...can be collapsed into this:

Tab increases indentation of list items.

Shift+Tab decreases indentation of list items.

Ctrl+K,C wraps the selection with HTML comments.

Ctrl+K,U removes HTML comments surrounding the selection/caret.

Ctrl+PgUp moves caret to previous heading

Ctrl+PgDown moves caret to next heading

Light Bulbs

Auto-generate HTML files

By right-clicking any Markdown file in Solution Explorer, you can turn on automatic generation of a HTML file.

Generate HTML

It will wrap the output rendered markdown in a HTML template that looks like this:

<!DOCTYPE html>



You can provide your own HTML template by dropping a file with the name md-template.html in the same or parent folder to the markdown file. If not found, it will search %userprofile%.

Just make sure to include the [content] token in the template. And the [title] token is optional if you need a title.
