using THIS_SCRIPT

[flat6]

I've got some of my own pages using the vB template system, and they all have something like...

define('THIS_SCRIPT', 'index');

I'm guessing this correlates to the display in the user activity screen, where it might say that a user is looking at the forums index. Where do I need to make the matching coding so that if I say define('THIS_SCRIPT', 'my_widget'); it'll display on the user activity 'user is looking at his widget'?
