So I just noticed in meta.discourse.com that when I typed safe mode in plain text, it automatically creates a hyperlink like this: safe mode
- Notice how in the editor I did not use markdown to make the word
safe mode hyperlinked.
What is this feature called? How can I enable it on my forum?
Thanks 
I’m pretty sure that it is this feature after doing a quick search:

You can use watched word to change a term into a link
@moin is correct, we use Watched Words to linkify eg safe mode, data explorer, standard install, etc, though the Auto-Linkify Words theme component has extra functionality if you need it. 
Both solutions are exactly what I was looking for! Thank you very much.
I chose the vanilla option by @Moin to reduce adding to many plugins.
