Ah, CTRL-Z. I’m sure at some point in our lives, everyone has wished they had the ability to go back in time and Undo something they did. The ability to undo, however, is rather commonplace in the computer world. It allows one to revert a document to an older state by negating the last action(s) performed and all of their consequences.
If you have used a computer before, I’m sure this feature has saved you numerous times. It’s so deeply rooted in our subconscious people sometimes use it without even thinking about it. If undo is so successful on the desktop, what is the reason for it’s almost non-existance in Web Applications?
