Typing Backwards in Eclipse

This is just a random tidbit, but I thought it was pretty cool.  I’m not sure if this is a hidden easter egg or actual functionality.  I was recently working in Eclipse and after an interesting keyboard sequence I was typing from right to left.  No matter what I typed within the current document it was displayed backwards.  I thought it was something buggy with memory consumption, but it turns out that none of my other files were behaving the same.  After I closed the offending document and opened it back up everything was back to normal.  Check out the screen below to see the goods.
