## Linking notes is very easy

When linking notes, you don't need to remember the full title of the note. Enter a fragment, and HackMD will search through all your notes.
All of them? Yes, across spaces, search your private space and all the team spaces you are part of.
Rest assured, you need the corresponding permissions to view the note's content.


>[!Note]Hint
>- Notes that have been viewed will appear in the auto-suggestion list.
>- For other notes, you can use Spotlight (shortcut <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd>) to find and paste them.

## Insert hyper-link with `[]`

You can add hyper-link to a string or sentence.

1. Input ``[]``, and choose ``[link text](https:// "title")``.
2. Replace the link text and the shared link.

### Example:

[BBC home page](https://www.bbc.com/news)
