When you refer to another bullet in RemNote, whether you do so with a Reference, a link, a portal, or a tag, RemNote creates a bidirectional link between the two bullets. That is, RemNote recognizes both that A is connected to B and that B is connected to A. The “backwards” link from B to A is called a backlink.

You can take advantage of backlinks to quickly jump around your knowledge base or find all the places you've discussed a particular topic.

In the right margin next to to any bullet that has been referenced (Nucleus in the following screenshot), you'll see a small number in a gray box. Clicking this number will bring up a list of backlinks. You can click on a backlink to jump to it.

When you zoom in to a document or bullet that has at least one backlink, you'll see a References section at the bottom of the page. It lists every place that document or bullet has been referenced.

Automatic search portals show the bullets that reference the document or bullet. You can directly edit and work with these bullets, just like you would in any other portal.

There's one other kind of backlink called a text reference. It appears when the name of a bullet shows up somewhere else in your knowledge base, even without a direct link. This helps you find places where you mentioned a concept without explicitly connecting it.

The text references portal is disabled by default. To enable it, use the Find Text References command from the omnibar. Once the portal is enabled, you can show or hide it at any time using the Hide/Show button. The portal will also become enabled automatically, alongside the references portal, if the document or bullet has at least one backlink.

To find text references without zooming into a document, highlight the text you want to find references for, then select 3-dot menu > Search from the floating toolbar. A dropdown of text references will appear below the toolbar. This will keep appearing every time you select any text. To turn it off, select 3-dot menu > Search again.
