Assign me to a task by hoving over it and pressing a mouse/keyboard button

We’re looking for ways to show many options to people that are collaborating on a single board, and have them vote on them. The voting mechanism we used in the past is assigning yourself to a task (voting option), on multiple tasks and then manually ordering the tasks based on how many faces are attached to every task.
This requires a quick way to assign yourself to cards to make it easy for toggling your vote on and off

Thanks!
