Now normally I would use Teamstudio Ives Analyzer to do this, and I probably will, but while on the http://www.teamstudio.com website I found this useful item:
Lotus Script browser: http://www.teamstudio.com/support/scriptbrowser.html
Also reviewed here: http://www.dominopower.com/issues/issue200504/00001532001.html
It allows you to see which function is in which script library, where a function or method or class is used and sorts them all alphabetically.
Quite useful, it works in the Lotus Notes 7.0 client as well.
It is also FREE ! Quite handy.
