Issue description

Trying to bind Alt plus a named key causes the error "Invalid Key"

        bind "Alt Tab" { NewTab; }
        bind "Alt Space" { NewPane; }

Some work e.g. "Alt F1" but some do not. Neither the documentation nor the error message make it clear if this is a terminal limitation or a zellij bug

Minimal reproduction
