Edit an entry as a note
Some entries automatically display the memo editing field on the right side of the window when clicked. Mostly this is true of Notes, Folders, and Books.
However, all entries (including Todo, Day, Anniversary, and Habits entries) actually also contain a similar memo field, which can be viewed and edited by selecting Entry menu > Edit as Note.
This command edits the entry as if it were a Note entry, showing its Title and Memo fields on the right side of the window.
