I can press F10 to open the menu (the same that can be opened by clicking the right-top menu icon). But as soon as it is open, I cannot use the arrow keys on the keyboard to select menu items.
Is this a problem in Rhythmbox, Gnome or am I doing something wrong?
This is with Rhythmbox 3.4.4 on Ubuntu 20.04 with Gnome 3.36.8.
