In RemNote, everything is a Rem (plural: Rems or Rem): a small, atomic unit of information. Most Rem correspond to bullet points that you type in the outline editor.

However, Rem aren’t always displayed in outline form, and RemNote creates some Rem itself. Examples of things that are Rem but often won't look like bullet points include:

Flashcards are an exception to this pattern. They are not Rem themselves; rather, they are associated with and generated from Rem. A flashcard arrow within a Rem causes associated flashcards to be created in the appropriate directions. When you edit the text of or delete a Rem, the associated flashcards are automatically updated.

Each Rem may have up to one parent (a Rem above it in the hierarchy, indented one level closer to the left) and any number of children (Rem below it in the hierarchy, indented one level closer to the right). We can similarly talk about grandparents, grandchildren, and so on, using standard family relations terminology. Collectively, all Rem higher up the hierarchy (parents, grandparents, great-grandparents, etc.) than some particular Rem are called its ancestors, and any lower down are called its descendants. A top-level Rem is a Rem that has no parent.

You can quickly jump to or select any Rem using global search (Ctrl+P, or Cmd+P on a Mac) or hierarchical search, or zoom in to it when you can see it in the editor by clicking on its bullet point.
