Even clearer would be to hide that in a constant rather than having a bare magic number . . . 

use constant HELP_KEY => chr( 8 ); ## Control H

if( HELP_KEY() eq $key ) {
  ## . . .
}

Alternately: 

use Readonly;

Readonly my $HELP_KEY => chr( 8 ); ## Control H

if( $HELP_KEY eq $key ) {
  ## . . .
}

    I agree, but it is different advice.

    I was making suggestions on how best to define the constant. You are suggesting that he should use a symbolic constant in place of the actual constant.

    Ie. You could have made your point by suggesting 

    use constant HELP_KEY => "\cH"; ## Control H

    And my point would still hold.

    As for Readonly; I "Just Say No", but that's apparently controversial :)
