Note that "^?" is DEL (ASCII 127), mapped to by some keyboard drivers when the
backspace key is pressed.
Backspace (ASCII 8) is "^H".

'case' does not evaluate the clauses. But as the value of BS is constant, you
can use a read macro
(case Key (`BS (prinl "BS pressed")))
But better catch both values:
(("^H" "^?") "BS pressed")
(T "Other key pressed") ) )
