But that's not really what the feature does, or what it was intended to do. It 
was added solely for the experienced user named Fernando who liked to type 
things fast without needing to use the shift keys. It was not a do-what-I-mean 
to correct newbie errors. There is certainly nothing in the message that implies 
that you *should* type things differently.
