Insert formatted text

[jasonw22]

I would like to save "chunks" of formatted text somewhere for later
retrieval. These chunks of text share a few characteristics:

* They contain multiple styles
* The layout (the position of the various styles in relationship to
each other) of the "chunks" is important and should be preserved
* The "chunks" each have a specific dimension that makes them suitable
for insertion in specific places within the parent document (and
unsuitable for other places within the parent document)
* A "chunk" is similar to a template, but it is only a fragment of a
document

You might call this "chunk" by various synonyms depending on context:
"module", "component", "sub-document", etc. The name isn't as
important to me as the characteristics listed above.

I want to create a template that contains the "framework" for a page
layout. I want several pre-defined "chunks" to be saved (but not
visible) within the template. I want the user to be able to click
toolbar buttons that initiate macros that insert named "chunks" in the
location of the cursor. Nice to have: it would be great if I could
warn the user when they are trying to insert a "chunk" in the "wrong"
place (based on the dimensions of the "chunk" compared to the
dimensions of the cursor's "container", or some other piece(s) of
data). Ideally I'd like to be able to distribute this template by
simply emailing someone a single .doc file (I would prefer to avoid a
system of multiple files that must be distributed together).

I can see several potential avenues for accomplishing something like
this, but I wanted to get some input from this newsgroup before I start
work.

Thanks,
Jason
