buffer gap

buffer gap

[A. Soare]

Can somebody explain me what the buffer gap is useful for ?

I see in elisp manual:

<< Insertion works by filling in part of
the gap, and deletion adds to the gap.  Of course, this means that the
gap must first be moved to the locus of the insertion or deletion.
Emacs moves the gap only when you try to insert or delete. >>

However, I cannot understand too much. Can somebody explain me the idea , please?

Thank you very much. I studied today the problem from your link and from http://www.finseth.com/craft/#c6.4.3 .

This is enough.

Thanks again,


Alin Soare.
