When you refer to another Rem in RemNote, whether you do so with a Rem Reference, a link, a portal, or a tag, RemNote creates a bidirectional link between the two Rems. 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.
Inline backlinks
In the right margin next to to any Rem 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.
Document backlinks (References Portal)
When you zoom in to a document or Rem 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 Rem has been referenced.
Automatic search portals show the Rems that reference the document or Rem. You can directly edit and work with these Rems, just like you would in any other portal.
Text References Portal
There's one other kind of backlink called a text reference. It appears when the name of a Rem 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 Rem 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.
Note: this text reference search is limited to 100 results, as returning more would significantly slow down RemNote.
