Keyboard access not working

Along with my other topic about typing an application name (which no longer works), selecting one using the up/down keys has never worked, which is kind of an annoyance when my hands happen to be on the keyboard (hence, the reason for using ctrl+alt+space). I would like to suggest making PA fully keyboard accessible, and that doesn't mean assigning arbitrary keystrokes to the buttons on the right, which is the case atm, but that means being able to navigate the menu by arrow keys and typing partial names.

This is PA 10.1.2.
