WorldScript info is available from Apple at 800/776-2333, so if you have questions about what script modules are available or how to get them, call that number and choose either 4 or 5 from the voicemail system. For the moment, only the Japanese language module (released last week) is available.
Option-Click in Scroll Bars for Jump Scrolling
In Mac OS X in general, and thus in most native Mac OS X applications, hold down the Option key and click anywhere in a window's scroll bar to jump to that spot (rather than scrolling one screen). If you like this behavior, you can make it the default in the Appearance preference pane. For "Click in the scroll bar to:" select "Jump to here."
