Greetings, I am trying to create a script that will read in a series of characters and look for a certain sequence of characters. I am having a hard time reading in control characters like <CTRL> and <ALT>. I'm basically am trying to create a keylogger that will look for a sequence like "<CTRL>+<ALT>+B" and execute another script when that happens. I've tried using the following code: 

my $key_buf;
my $sequence = qr/some_keys/g;

system "stty cbreak < /dev/tty > /dev/tty 2>&1";
while (($key=getc) ) {
                                                            
    $key_buf .= $key;
    if ($key_buf =~ $my_sequence) {
        system "xmessage 'OH YA!'";
        last;
    }
    last if $key eq "q";
}

system "stty -cbreak < /dev/tty > /dev/tty 2>&1";

I've also tried using Term::ReadKey and Term::InKey, but I've had no success in capturing the control characters. Any suggestions or anything I'm missing?

Thank you.
