Table of contents от Nathan Manceaux-Panot

Table of contents is an extension for quickly navigating documents.

In any web page with sections—an article, a documentation page, etc—summon Table of contents to see a list of all headings in the page. Click any to jump to it instantly.

The list supports click-and-drag selection, arrow key navigation, and type-to-select. You can also invoke the list by pressing ⌃G (macOS) or Control+Q (Linux, Windows).
