A trivial question: how can I change its text? I'm writing my game in Italian and i'd want that hyperlink to print "Continua" instead of "Continue".
Thanks.

Never mind. It was not easy to find, but finally I found it.

If you look in the bottom left hand corner you'll see the word 'Filter'. Click on that, then a box will appear, 'Show Library Elements'.
Click that. All the background Functions, templates, commands that make quest work are then shown in the game tree. In the search box at the top of the tree, type 'continue', then press the little magnifying glass next to the search box. The Template name is 'ContinueLabel'. You will need to copy this template into your game in order to change the wording of the label.

I solved it in a more banal way: I just put request (SetInterfaceString, "ContinueLabel=Continua") into the start script.
