[OS X TeX] Recovering from typing errors

[Nicola Cabibbo]

Dear MacTexers,

Since the introduction of autocompletion in TexShop the frequency of  
errors I
make in typing mathematics has been drastically reduced, but I must  
confess
I still get quite a few. This often requires re-typesetting twice to  
re-produce the
correct references, table of contents, etc.

Would it be possible to avoid the second run by making a backup of  
the .aux
file and restoring it in case of an aborted typesetting? I realize  
that in
certain cases a second run is required, e.g if new labels have been  
introduced,
but in many cases it should not. Where should such a modification be  
introduced?
in texshop itself, or in an ad-hoc script? Is this possible? Is it  
difficult?
Is it dangerous?

Thanks for any help on this  (not very important) problem,

	Nicola Cabibbo
