As vi(m) users keep telling us, actual editing is much less frequent
task than navigation etc., and they like the fact they can do navigation
etc. very conveniently with one-key commands in read-only mode in their
modal editor. 

I wrote navi-mode.el for this vi(m)-like experience when working with
org-mode or source-code buffers in emacs - one-key commands in read-only
mode for navigation, structure editing and a kind of remote-control of
the associated source buffer.

The remote-control commands were restricted to act on outline subtrees
before, but today I generalized them to act on the 'thing-at-point',
wether an outline-subtree or an sexp - using mark-sexp.

Now you can mark, copy, kill, query-replace, isearch, yank (and probably
more) not only outline-subtrees but also defuns, lisp expressions and
even plain-text words directly from the *Navi* buffer without switching
to the associated source-buffer ... thanks to mark-sexp's quite sensible
behaviour even outside its original scope.
