[JS CS3] Add shortcutKey to Button?

Question

I wrote a script with a UIdialog asking for replacing several things or not. It works fine but I'm not able to add a shortkey to my "replace"-button?
Did anyone know what I've forgot or done wrong?
var myDialog = new Window('dialog', 'Search and Replace', undefined, {maximizeButton:false, minimizeButton:false});
with(myDialog){
    with(add('group')){
        myReplaceButton = add('button', undefined, "Replace", {name:'ok'});
        myReplaceButton.shortcutKey = "F3";
        myReplaceButton.onClick = function(){ myDialog.close(1) };
        myReplaceButton.onShortcutKey = function(){ myDialog.close(1) };
        myCloseButton = add('button', undefined, "Cancel", {name:'cancel'});
        myCloseButton.onClick = function(){ myDialog.close(2) };
Regards

Are you sure? ...
I copied your original script, added 'myDialog.show()' at the bottom. Hotkey "F3" didn't work. Changed it to 'r', and it worked. I'm on CS4, and some ScriptUI features changed just a bit, so I tried the same in CS3. It worked there as well. Really.
The hotkey, by the way, is plain 'r', not with alt or shift or control down as well (or option or command -- okay, that's a joke). Add this alerts
myReplaceButton.onClick = function(){ myDialog.close(1); alert ("okayed"); };
myReplaceButton.onShortcutKey = function(){ myDialog.close(1); ; alert ("okayed by r"); };
myCloseButton.onClick = function(){ myDialog.close(2); alert ("cancelled"); };
and you will able to see which event occurred.
