Confused by show/create shortcut

I played with shortcuts a bit, I got confused that agenda just seemed to have a show/create action and that was it. Then I discovered callbacks but that wasn’t right either - I could only get the title to be 18 (spaces seem to be an issue). Turns out you need URL’s instead!

Right—wrapping the text in a URL action seems to encode URL-unfriendly text characters, like spaces, in order to make it work.
