What gets bound (or tries to be bound) to the key is the sexp (let...),
not its value (which is a command).  That sexp is not a command.

Remove the quote to have the (let...) be evaluated, and bind its value.

But that is likely not what you want.  I'm guessing that you want to
bind the key to a command (which you would write) that would, itself,
bind `b' etc. and then invoke whatever other code you want.
