[CONNECT] MicroStation Help fails to mention Active Scale

While attempting to answer another question here, I searched MicroStation Help for Active Scale.  I can find it nowhere. 

The Help Key-In Index mentions ACTIVE COLOR, ACTIVE LEVEL and many others, but omits ACTIVE SCALE.  Neither is its abbreviation AS mentioned anywhere I can find. Please include some help about ACTIVE SCALE!  

In general I find the HTML help very convenient.  However, its indexing and search tools are wanting.
