AZERTY shortcut ALT+[NUMBER]?

I am trying to use the shortcut already native in UE4, but it seems impossible to do the ALT+[number] shortcut from my keyboard.

CONFIG: standard AZERTY keyboard, with windows 10 & UE 4.21.2.

When i’m in the Editor preferences > keyboard Shortcuts, I try to replicate a ALT+[number], but all I can achieve is ALT+quote, ALT+left parenthsis, …

I tried with CAPS locked and unlocked, I tried with ALT & ALT GR, and I tried with MAJ, nothing create a ATL+[number] shortcut.

Do I have to create other shortcuts for all of thoses ?
