Rotate Everything By 13 Letters

For some inane reason, Vim comes with a ROT-13 feature. So, if you are ever in need of rotating the letters of some portion of the file by 13, you can do that with the simple g? binding.

For example, if you hit g?? on the following line:

Six dollar eggs

you will get

Fvk qbyyne rttf

As you can see, casing is preserved.

The only practical uses of this are Vimgolf and convincing people at coffee shops that you are a hacker.

See :h g? for more details.
