Yes, it's fairly simple, but I don't feel inclined to devote the time. I disagree with Bee-Dub that writing backwards is much more difficult than typing backwards, since you produce the characters in the normall order when you write backwards. Nealry all of us lysdexics cna od taht fiaryl smiply.

When typing backwards you have to create characters in reverse order, and that's just time consmuping.
