allow keyboard input (navigation) for image picker (and similar functional panels)

I regularly insert images into objects.

Often this is a repetitive task, with things like wanting to insert cover images as body images as well, pick from recent images for other objects etc.

It would massively improve such repetitive steps/workflows if one could "navigate"/control the pick panel via keyboard. (I guess there are some other panels inside Capacities where this would also be useful as principle…).
