>Or reverse sort till the end of the file with !Gsort -r^M etc. Right. Or flip the case of a section of text, even of an arbitrary block of lines demarcated by marks set by vi(m) commands like ma and mb and the like, by filtering it through tr. Or filter another section through sed or awk or even through a Unix pipeline, to do whatever you want. And with just a little practice, you can become fluent and fast with all of this, and it improves your productivity a lot, apart from being fun and creative.
