Unless you show some of your code, you are only going to get generic answers.

use warnings;
use strict;
use Tk;

my $top = MainWindow->new;

$top->Button(
    -text => 'Push Me',
    -command => \&mysub
)->pack;

$top->bind('<Return>', \&mysub);

MainLoop;

sub mysub{
    $top->Label(
        -text => 'You pressed it!'
    )->pack;
}

my code was basically that posted by thundergnat my problem was that i was getting the function called when the program first ran (i guess coz i had to hit return to run the program) i thought i was going about it completly the wrong way but obviously not coz now it works so thanks a lot

i have been trying to use bind but am getting a sensible result

You got a result that made sense? Did you want it to not make sense?

I know you just had a typo, but that was just too funny to pass up. :-)
