I think my dream keyboard would have a slightly wider Tab that would be split into two, Back Tab and Forward Tab.

Tab is such a heavily used key that it would be nice to give it more to do, and free up ⇧ to mean something else, too.

@mwichary I'd switch caps lock to be a second enter as first choice but do also like your idea

I'm used to either have tab as text or ->| style symbol neve the up arrow
