Trello Shortcuts - Checklists

Has anyone got a shortcut working that creates a card in Trello with a checklist? Equally useful to me would be adding a comment with a checklist.

Two barriers I’ve encountered:

  1. I don’t know if I can use their pseudo-Markdown to create a card.
  2. Their syntax guide promises to show the syntax for a checklist but never does. (I would guess it’s [ ] - with or without the space - but I don’t know,)
