This is quick and dirty and not terribly maintainable. But it's very useful for creating quick cards from the terminal. Requires familiarity with Trello and a basic understanding of bash.
Make note of the token. Replace any mention of YourTrelloToken with this looong hash.
Pick a reasonable number of the most popular boards you use. Grab the URLs of those boards. At the same time, think of short, one-word, easy-to-remember names for each board (e.g., work, homeprojects, wedding).
Grab the board IDs of the boards you chose. It'll be the ~8 character hash-like string in the URL. E.g., for https://trello.com/b/aWsGTrsD/work the ID is aWsGTrsD
Look at the resulting json, and, for each board, decide on the list (e.g, bullpen, doing, To Be Done) where you would most likely put a quick placeholder card (the list won't be dynamic, only the board). Make note of the 'id' property for each chosen list (one per board).
Make note of your new values that pair short board name with list id property. E.g. -- work => wjeh18ehdkqwjeh7y1987
