+1 !

Especially as you need to raise and lower the small finger up and down
during typing as your example could also easily result in !"=/:FF/=
at least on a German layout ;-)

I'd be happy satisfied enough if "| inc" would be case-insensitive. Or is 
there an option I missed? Or a thoughtful reason to leave it as it is?
