I was under the impression (from a previous post on this forum) that pressing F1 would get me there. Not. I've got v1.5, installed through the Command Center. Anybody know how to get at it?
 
Actually, just in case it's not covered there, does anyone know the secret code for interpreting the Preset names?

Try clicking somewhere in the DPro UI itself before hitting F1. The default location for the documentation is "C:\Program Files\Cakewalk\Dimension Pro\Documentation."
 
WRT abbreviations, it depends on the context. Many of them are the initials of the sound designer. There are a few threads about this subject

First thing I tried. Standalone or VST, all I get is the little blue whirly thing for a few seconds.

Search for WRT Abbreviations turned up zilch. WRT means what?

Oh, With Regard To. How dumb I am. OTOH, search for preset name abbreviations and variations on that theme also turned up zilch. Maybe someone else can come up with a better search method? Moderator?

Like this one http://forum.cakewalk.com/FindPost/805167
I have seen others but I do not recall seeing a complete list of abbreviations
When it comes to searching the forum, I  use google and add site:forum.cakewalk.com to the search string

 
For the DimPro help file / manual to load on F1 you have to first rename the file "Dimension.chm" file to "Dimension_Pro.chm".
