Twin Anchors is a deliberate reading instrument for comparing distant passages in one document. Click the extension on the current page, choose Set A or Set B in the on-page rail, then click a paragraph or heading. Jump with the rail or the [ and ] keys when you are not typing. Anchors follow their original text element as a dynamic page changes, rather than staying tied to a fixed pixel position. Marks last for the current page session and disappear when you close the instrument or navigate away. It does not index your browsing history, run automatically on other pages, or send page text to a server. Browser and other protected pages cannot be annotated.
