stupid dumb idiotic simple question about keystrokes

[theapeman]

Sorry to bore everyone with this question, which I'm sure is the equivalent of "Please help! What letter comes between C and E in the alphabet?" but seriously, if you really didn't know that, I don't know if there's a single google search in the world that would actually help you...

Anyway, here it is: I'm writing a Perl script that uses the Expect module to open Firefox, and then I want to send Firefox a "CTRL+RightArro w" command, like so:

use Expect;
my $command = 'firefox';
my $URL = 'http://some_url';
my $key = 'i have no earthly idea';
 
my $exp = Expect->spawn($command, $URL) or die "Cannot spawn command: $!\n";
# do some stuff here, and then...
$exp->send($key);
 

where $key is CTRL+RightArrow .

Dumb, right? Sorry. Just pretend I'm in nursery school. : )

P.S. just reading the answers to other people's questions on this site has helped me a lot -- this is the first time I've ever had to post!

search for "IBM scan codes" on google, I think that is what you want.

Holy smokes, thanks! Knowing what to google really helps! I even found this site that has a keyboard emulator. You just enter the keystrokes you want and it returns the codes.

So what I got for CTRL+RightArrow was essentially 4 keystrokes:

14               # CTRL key down.
E074             # Right arrow key down
E0F074           # Right arrow key up
F014             # CTRL key up.

So my question now is, what is the syntax for assigning those codes to my $key variable?

Thanks again.

I'm just guessing:

my $keystroke = '14-E074';

give it a ty

[KevinADC]

or maybe its:

E012E074

that what the emulator shows for both keys down
