For instance, many of GitHub READMEs include this feature. Each heading gets an anchor, and the viewer can hover over the heading to copy the link. The customer support engineers at my company would like an easier way to provide links to customers than viewing the page source and finding the `id` of the section that they want to link to.
Here's an example of a GitHub page w/ this feature: https://github.com/Appdynamics/AppDynamics.DEXTER/wiki
I haven't found any addons or even read any information about this being possible. The only thing I can think of is to update the Doc Theme template, but I'm hoping there is a simpler solution.
