Page up and Down keys that are subkeys on the numpad not working

I got a new laptop and the page up and down keys are activated by shift+numpad9 for up and shift+numpad3 for down. The issue is that this isn’t recognized and won’t do what I want so to scroll on item menus I have to use the mouse to drag the slider. Aside from rebinding those functions to different keys is there anything else I can do?

You’ll have to rebind them. It’s pretty normal to have to shuffle some keys around on a non standard keyboard
