showMessage() is triggered on any cursor action. That's way too often.
E.g., it would fire down statistics unnecessarily if you move with the
arrow keys through your document.

And I am not completely sure each relevant action triggers a message.

You need a more suitable signal that only emits when text is edited or
loaded.

You can use lfuns e.g. via the LyXServer mechanism or pipes. This can
also be used to insert text or citations.
