This has got me scratching my
bald head for a while now

Why is it not possible to undo smiley or BB codes that one may have clicked on accidentally in a post they are trying to create? With CTRL + Z It's sort of convenient, you know, especially if you have been used to typing in different sorts of apps on PC.
Was the undo (CTRL + Z) option disabled on purpose? Or can our script guy (PowerGlove) make some patch?
