The keyboard shortcuts in trello are almost "too short." Please, can you consider requiring "shift" or "control" as part of the command, to make it more intentional?
I can't tell you how many times I have accidentally archived a card simply because I started typing "c" - the first letter of many a coworker's first name - when I thought I was in a dialog box on a card. I often catch the error and see the archive banner, but a few times in the haste of work life, I have not seen the banner only to discover an important task got archived. Thanks for considering.
