You’ve probably worked it our already, but cmd-L in the note to link from, then drag the Scap-map to link to into the resulting box. You have to add file:// in front of the other gubbins to get the syntax right. It’ll take three clicks to activate: one to select the note, one to get it in the right mode (I nearly wrote `mood’ - what was I thinking? On a Tuesday?) and then again to activate it.
Once it’s working you can very easily get hooked on the power …
Cheers,
