When using any editor other than emacs I really miss shortcuts for:
  * Uppercasing, lowercasing and capitalising words.
  * Exchanging adjacent letters/words.

Does TeXmacs (or any popular packages for it) do this?  If not, would
it be easy to write a package?  I'm an experienced programmer, but new
to TeXmacs internals.  If this would be a straightforward project I'd
like to give it a go, but tips would be welcome.
