This is just a example, I may not have understood your post and the person who answered it but I think you are going the hard way around all this, say your device is a dvd player, just use one of the templates in the editor find the make and model you want save all, your template will now have all the codes assigned to the correct buttons, create a new blank page now go to the view menu and from the drop down select both simulated & pages then just copy and past action from the desired buttons to your custom template, I have found this a quick and easy way to pick and choose what buttons I or the client want on there custom interface...Hope this helps Mick
