Set `Ctrl + Shift` as key combo prefix for numeric keys [fixes #78750882]

`Alt Gr` is interpreted as `Ctrl + Alt` in web browsers. Key bindings with `Ctrl + Alt` prefixes block typing characters that can be typed with `Ctrl + Alt` or `Alt Gr` key combo prefixes in some keyboard layouts with Windows operating system.
and please keep brackets here, that is a native shortcut people are used to it.
