italian keyboard problem with brush paint delete and grave accent key

I am following many tutorials regarding the latest version of Photoshop 2020. In this version there is the possibility of using the brush and erasing alternately with the tilde key. However, Tilde does not exist on the Italian keyboard, nor does that of the grave accent that you have indicated as an alternative exist. I therefore ask technical support to indicate a valid key for the Italian keyboard or to find an appropriate solution.
