The DIMENSION keyword is *new* when judged by the "all these years"
standard.  It first appeared in IDL 5.1.

If you are interested in important keywords, I've found
SMOOTH(/EDGE_TRUNCATE) indispensable, as well as CONVOL(/CENTER).  I
don't do *that* much time series analysis but it seems I always need
these keywords when I do.
