Using OneNote as a Wiki

I’ve been using OneNote for years, but this eluded me throughout all of that time:

You can easily link to pages in the same notebook by just typing [[Page Name]].

OneNote will auto-link and remove the square brackets if it finds a match, or underline with a dotted line and create a new page if you click through.

So far I haven’t found a way to link across different sets of subpages, but this is handy enough.
