If you have an I-DEAS background and you're using NX now, this environment setting is definitely for you. Most ex-IDEAS users I've seen complain that (well they complain about a lot of things) the rotate/zoom/pan stuff in NX is 'different'. *To have the same usability, set UGII_FKEY_DYNAMICS=1, and you'll have the F1, F2, F3, F4 keys working just like they did in I-DEAS: Zoom, rotate, pan, etc.
*: If you haven't used I-DEAS before and you like these, then all I can say is that you've gone to The Dark Side.
