Typing @ and picking a list links to it, and the linked list keeps a backlink to every thing that pointed at it.

Why you'd care

Sublists nest, which is a parent-child relationship. Linking is the other kind: two lists that relate without one owning the other. A person's list mentioning a project, a day mentioning the trip it was part of.

The useful half is the reverse direction. Open the project and you can see every day that referenced it, without having tagged anything.

The 60-second version

Type @ inside a thing, start typing a list's name, and pick it from the menu. The link is created, and a backlink appears on the other list.

Going further

It shares a menu with mentioning people. The same @ menu offers people on shared lists, but that is a separate feature that notifies someone. See mention a person.

Backlinks are automatic. You never create one. Linking is the only action, and the reverse side maintains itself.

Backlinks show up near the top of the list. A Linked from section lists every thing that links here, grouped by the list it lives in. Those things are real rows, so you can check one off or edit it right there without leaving. Tap the list name above a group to jump to it. Tap Linked from to fold the section away. It starts folded if you turn on Settings Lists & things Collapse sections.

Dead links go inert. If the linked list is deleted, the chip becomes plain text rather than a link to nothing.

Universe draws these. The Universe graph has a Backlinks dimension: every list you have linked becomes a line from the list the thing lives in to the list it points at. Tapping either end shows the text of the linking thing, so you can see what the connection actually was.

Tips

  • Link a project list from your day rather than duplicating the note into it. The backlink does the filing.
  • Linking is better than tagging when there are only a handful of connections. Tags are for patterns, links are for specifics.
