Yes that little question mark really should be functional. After Autodesk bought and then canned Softimage, the online help documentation was disconnected yet bizarrely it's still on their site. On the odd occasions I launch soft and need to check something those marks bring up a 404. Defunct software I expect this in, TG not so much. I'd call this documentation a high priority because as WASasquatch notes, even those of us who've used it for years, and definitely those who are enthusiasts, need it.
