This happened to me by accident when I added this as the first line of a calendar note, and it deletes the rest of the text in the note if there is any.
First I wondered if this was a feature I didn't know about. I’m keen to learn more about calendar features, but it seems to be some undocumented behaviour or maybe a bug/accident.
Any thoughts to share on this?
