Some time ago I published a generic Undo handler for use in Excel VBA on this blog.
In that article I promised to write up how the internals of the technique work.
I’ve published a new article on my website that explains how things work.
Also, I’ve added some functionality to each of the pages of the article so you can add your comments on the page itself. Comments written by you will be shown on the same page immediately, giving the pages a blog-like feel to it.
Enjoy (and write comments)!
