Trello supports referencing one card from the description and comments of another card by using the referenced card Short ID. (More info here.)

The only ways I currently know of detecting a card Short ID is:

  1. Entering into the card and looking at the "Card #" legend at the bottom of the right column.
  2. Hovering with the mouse over the card and looking at the last part of the URL. It might say something like "/22", so in that case the short ID will be 22.

However, both of those methods are quite uncomfortable when you're writing the description/comment for another card.

I wonder, is there any way of having Trello autocomplete/suggest the Short ID for a card, or help with the referencing?

When you are entering info on a card, type "#" then whatever your search term for the card is and it should start matching cards for you.

For example: #fix should find all cards that have "fix" in their titles for you.

With this, you don't have to know the shortcode.
