[Koha] Wrong shortcuts in Koha menu "Cataloging"

Hi There are three shortcuts or hotkeys in the Koha staff client: * Alt + U = Check out * Alt + R = Check in * Alt + Q = Search the catalog As I understand these shortcuts should work all over the staff client, and mostly they do. In Koha 3.20 though when going to Koha menu "Cataloging" they don't work as expected. Here the mapping is: * Alt + U = Search the catalog * Alt + R = Cataloging search * Alt + Q = Check out Is this a bug or do I miss something? Kind regards, Michael
