add hotkeys for filing into specific folder per account (for archiving messages)

Would it be possible to add a hotkey that instantly moves a message to a specified folder per account (and ideally also marks the message read). This would be great for archiving emails.

Start by reviewing the Quick Folder Move add-on's existing hotkey and message-moving entry points, then determine how account-specific destination folders are represented. Done means a hotkey can move a message to the configured folder for its account and, where included, mark the message read; the issue does not name files or tests to run.
