how to collapse a horizontal into vertail

how to collapse a horizontal into vertail

[Zimmen Gnauh]

   shell command tr can be used to collapse a sentence "this is a test" into 
this 
is
a 
test
. How can this be done in emacs?

(replace-regexp " " "^J")

or M-x replace-regexp, similarly. Use C-q to quote the C-j.

Works t'other way round, too :)

    this would replace all " " with "^J". However, the text I'd like
to  replace is only part of the buffer. I expect to mark the region
first and then do something to collapse it.

You could use the narrow-to-region function (C-x n n) to shrink the
affected area to a selected region, then widen (C-x n w) to regain view of
the whole buffer.
