Interactivity has always been a one of RAVE's cornerstones, since the very first prototype. The current version contains a mix of new C-based functionality, and the functionality that is largely Python-based that was written a few years ago. This hybrid solution is not going to last, and currently the way to distinguish between old and new functionality is that the old modules are documented using Python's pydoc system, whereas the new functionality is documented using Doxygen. So if you see it in this set of documentation (not just this page), that means it's been migrated to the new system.

One battle-tested method of learning how the interactivity works is to take a look at a RAVE production script and break it down interactively on the command line with input file(s) off line.
