MAC option key in sc editor

Hi.

I have a big problem. I switched from WIN to MAC. I don’t have a US keyboard set, but a SLOVAK keyboard. Safari or Mozilla browser. When I switch to the scriptcase environment (v9.10 but also v9.12) the option (alt) key is blocked. Why? For this reason, I can’t use all the keyboard characters activated by pressing option when programming. These are the characters #&@<>[]…, which is a big problem when programming.
Can someone help me? Please, not the advice “Install a US keyboard”

Thanks…
