Internal links are links to other notes within Trilium.

You can open an internal link by clicking it. You can also see a read-only preview of an internal link's contents by hovering over it.

Inserting internal links

Internal links can be created at the current position in a text note by:

Pressing Ctrl + L or the button underneath the menu in the Formatting toolbar.
Searching for the title of the desired note to link. It's also possible to create new notes from this dialog by typing a non-existing note title and selecting either Create note, which places it in the Note Inbox (today's day note, or the top level, when no inbox is set), or Create child note, which places it under the note being edited.

There are two link types which you can select when creating the link to the note:

Link title mirrors the note's current title
1. This is sometimes also called "reference link".
2. The title of this link cannot be changed. Instead, it will always show the current title of the linked note.
3. The icon of the linked note will also be displayed.
4. If the linked note is deleted, the link keeps the last title it showed, in red and with a icon instead of the note icon. Clicking it while editing opens the Fix link dialog, which searches for that title; picking a note, or creating a new one, replaces the link with one to that note.
Link title can be changed arbitrarily
1. This will create a traditional hyperlink, where the text of the link can be different from the note title.

In-place linking

You can also insert internal links “inline” by using the @ symbol:

Type @ in a text note, which will open the note search menu.
Search for the desired note's title by typing a few characters. Use Up and Down to select the correct note, and press Enter or Tab to create the link. It's also possible to create new notes with this method by typing a non-existing note title and selecting Create note or Create child note, as described above.

You can also insert internal links by copying a note from the note tree.
