How to link to a named anchor in Multimarkdown?

In standard Markdown, place an anchor <a name="abcd"></a> where you want to link to and refer to it on the same page by [link text](#abcd).

(This uses name= and not id=, for reasons explained in this answer.)

Remote references can use [link text](http://...#abcd) of course.

This works like a dream, provided you have control over the source and target texts. The anchor can even appear in a heading, thus:

### <a name="head1234"></a>A Heading in this SO entry!

produces:

A Heading in this SO entry!

and we can even link to it so:

and we can even [link](#head1234) to it so:

(On SO, the link doesn't work because the anchor is stripped.)

If you have headers in the markdown files, you can directly link them in the file.

Markdown Header:

## The Header

this will generate an implicit id #the-header (replace internal spaces with hyphens and make lowercase).

To navigate to this id, you can create the link like this:

[Link to Header](#the-header)

This is equivalent to:

<a href="#the-header">Link to Header</a>

Please note the reference's name is a lower-case #header.

Taken from the Multimarkdown Users Guide (thanks to @MultiMarkdown on Twitter for pointing it out)

[Some Text][]will link to a header named “Some Text”
e.g.

### Some Text ###

An optional label of your choosing to help disambiguate cases where multiple headers have the same title:

### Overview [MultiMarkdownOverview] ##

This allows you to use [MultiMarkdownOverview] to refer to this section specifically, and not another section named Overview. This works with atx- or settext-style headers.

If you have already defined an anchor using the same id that is used by a header, then the defined anchor takes precedence.

In addition to headers within the document, you can provide labels for images and tables which can then be used for cross-references as well.
