Smart way to tag everyone in a discussion

[MortenCopenhagen (Morten)]

I was wondering if there is a shortcut to tag everyone participating in an ongoing discussion. Something like “@all” or “@everyone”.

Thanks in advance.

I don’t hope my examples triggered a ton of notifications…

For notifying everyone who participated in a topic there is @here.
There are some site settings to configure who can use that and when the notification is skipped because too many users would be notified.
