The most versatile method to manipulate an LO document is to get the internal UNO objects and manipulate them. Using the model provides significant control, but you must understand much about the different services and interfaces. Another method, which requires very little understanding of the LO internals, is to use a UNO dispatcher. The macro recorder uses the dispatcher for all commands. The dispatcher requires (1) the command to dispatch such as ".uno:Undo", (2) arguments that control the dispatch, and (3) an object capable of performing the dispatch. When writing your own macros, it is usually better to use the object model rather than the dispatcher. That said, some things are best handled by the dispatcher; for example, controlling the clipboard. The problem with using the macro recorder are that:
1. The dispatches are not documented and are stated to be subject to change; although I have not seen them change over time.
2. The recorder ignores some values from dialogs that are opened while recording a macro. It is possible, therefore, that you will record a complicated macro that will not actually playback everything that you did. One example is CSV import, the generated macro does nothing. I just verified that this is true.
Side note, my book OOME, which is available as a free download, contains a macro that will enumerate the supported dispatches. Last time I ran it, it generated over 300,000 rows of dispatch commands.

Subject: Re: Enabling Calc macro recording
It may not record input from a dialog. As an example, if you import a CSV file, I think that it does not remember the parameters that you used for the import.
The macro it produces does not use commands that directly modify the underlying object model but instead build an object to encapsulate each call and send that object. This can make it more difficult to modify the created macro.
