Macros in RAC2010?

[clog boy]

Not sure if it should be or have been discussed here, but I noted that RAC2010 now has a Macro feature. What's the use? I believe it supports C# and VB.net. The VB.net appears to have syntax similar to the macros in Office Word.
Could it be used to select and replace annotation styles etc? Could it be used to delete text styles and create new ones, in the same way throughout multiple files? In other words, could it be used for administrative template management actions?

RAC2009 has it too.

You can do a lot with it, but only if you're familiar with VB or C#, and know a little about working with an API.

It's not a simple macro system like Excel or Word has.

Well, I do know a fair bit PHP, and a little Javascript. So, OOP with variables and DOM are not new to me.
