sorry for not replying sooner
I hope you mean 1.1.10 not 1.1.1 which is awfully old. Even 1.1.10 is rather old, upgrading gmb is not that hard, you can just replace the files. You can also just run the new version without installing it, though the format of the gmbrc file may have changed which mean you can't go back.
Anyway, configuring your keys depend on your window manager/desktop, so I can't really help you, especially without knowing which one you use.
For shuffle mode, you'll want this command :
gmusicbrowser -cmd ToggleRandom
