Try changing "^H" for "\cH" or "\x08". "^H" is just a 2 character string consisting of the characters '^' & 'H'. The other two are escape sequences that perl interprets at compile time and substitutes the approriate single control chracter, chr(8).

Indeed, it might be clearer to others and yourself later if you used 

if ($key eq chr(8) ) { #Help Mode!
