I have come across a number of mentions of MultiMarkdown\'s support for internal links / named anchors but I am unable to find a single example of how to actually do it.
Here is my solution (derived from SaraubhM's answer)
**Jump To**: [Hotkeys & Markers](#hotkeys-markers) / [Radii](#radii) / [Route Wizard 2.0](#route-wizard-2-0)
Which gives you:
Jump To: Hotkeys & Markers / Radii / Route Wizard 2.0
Note the changes from and . to - and also the loss of the & in the links.
