Learning FrameMaker terms...

Dear all,

Digging through the FDK documentation and a list of commands generted from the app object, I come across terms that are not explained anywhere. What is/are:

• Key Catalog
• commands ThemeLoad, ThemeSave ("theme" does not exist in FDK reference)
• commands ShowNextKit, ShowPrevKit (there are "rmkits" connected to DITA, but kit?)
• command WinSlavics (has same ESC sequence with ShowNextKit and ShowPrevKit)

Any enlightment possible?
