Label Links
A perfect time to add a label is while writing or editing a page – when you are really intune with what your a conveying. With label links you can use labels just like you would #hashtags on apps like Twitter.
Enabling label links
Simply go to "Space Settings" -> "Integrations" -> "Magic Labels Settings" to enable label links for your space.
Using label links
To use label links simply type a single # followed by the label you want, like 'requirements'. When you then publish your page, Magic Labels will turn #requirements into a clickable link to all pages with that label in the current space. It will also add the label to the current page.
