Procedural File: translation_keys.inc.php

Defines keys that are used for text translation. Every string of the user inteface used within SWC is defined with a unique key within this file. User interface print-out functions are using T function with a key from within here to retrieve the right translation for the wanted text.
A key is basically an integer value. To add new keys, simply append the list and use $idx++ as unique value.
