A sitewide change only to the text that people see.

I'm sure this has been asked before, but I can find no reference.

I want to change every instance of the word 'Shipping' to 'Postage' - Nicer for us in the good old UK!

Now I can do a find/replace easy enough, but that will change my code too.
for example, I want to change this:

define('CART_SHIPPING_METHOD_TEXT', 'Available Shipping Methods');

to this:

define('CART_SHIPPING_METHOD_TEXT', 'Available Delivery Methods');

Ideas/commenst anyone?

Thanks again.

Run your search using the Admin> Tools> Developer's Tool Kit and make your changes in the language files using the overrides system.

Thanks for the prompt reply.

That's pretty much what I had been doing, but I really hoped for a 'one-click' sitewide change.

I guess manually doing it isn't too slow.

Cheers
