[Q] Cart Contents Checkout - Tweak Payment Button?


[font=verdana,geneva,sans-serif]Happy new year (am I still allowed to say that?) :P[/font]

[font=verdana,geneva,sans-serif]I would like to make a minor modification to the checkout area, but am having trouble finding the correct file(s) responsible.[/font]

[font=verdana,geneva,sans-serif]When you got through the checkout steps (or the single page checkout), when you get to the end (and have Paypal configured) and click Checkout, I would like the checkout to open in a Modal Dialogue or New Window (with everything removed except the URL bar).[/font]

[font=verdana,geneva,sans-serif]I know how to do that, but I cannot find which files are responsible for creating the button {button_xxx} etc.[/font]

[font=verdana,geneva,sans-serif]Thank you very much for your time.[/font]
