Keyboard Alphabetic Navigation In Any Filter List Of Actors, Tags etc

[Tell us about your issue, steps to reproduce, expected and actual behavior]
The filter list for actors for movies doesnt respond to alphabetic navigation using the keyboard. Its too long to scroll through. This makes it useless.
Can be reproduced by simple navigation to the said list & using alphabetic keys to navigate directly by pressing the keys "Hugh Jackman". This doesnt work.
This should allow for navigationdirectly.
