Sometimes you may want to link a section lower down on the same page, or link to a specific section on another page. Run will be upgraded in the next few months to an easier process for this, but in the mean time, this can be done manually. Keep in mind that once we upgrade this, your links may need to be recreated.
To start, you'll need the "ID" of the section you want to link to. Right-click on the Block you want to create the link to and click "Inspect", "Inspector", "View with Inspector" or anything that sounds like that.
Once the Inspector is open, you can hover over different sections, and you'll see them highlight on the page. For the Block you want to link to, copy the ID out of the "div" that corresponds to your chosen Block.
Now, you'll need to need to manually make a hyperlink for that section, by combining the link to the page with the ID as follows:
Notice that you'll place a # between the URL and the ID
Wherever you'd like to add your link, within the Add Link popup, paste that link under the Web Address section, and voilà!
