Re: v6: still no multiple undo?
The minimal approach to Undos is part of the reason why I created the notebook backup and tracking functionality that I include in A WorkLife FrameWork (shameless plug!). It is sort of a mini CVS in Mathematica. I do think though that Undo is tricky in Mathematica. One reason is that some of what one does and might want to undo can be **very** large. Another is the question of what one means by Undo and redo. Does this include evaluations? Does it include formatting changes? And so on. I suspect that the question is rather more complex than what one might have to deal with in a simple text editor or word processor. But, on the other hand, I am sure that some cleverness could be brought to bear on this... --David http://scientificarts.com/worklife Now Mathematica 6 compatible On Jun 7, 3:54 am, Selwyn Hollis <sh2.7... at earthlink.net> wrote: > Ah, that's at the top of my gripes list too.
