Thanks Tassilo - but this isnt showing me how to actually do anything
myself with the text string contained by the region if you get my
meaning.
I tried reading the code in boxquote, but there are too many function
calls not documented.
Maybe you could help?
I want something like this to work on a buffer region
(defun remove-vowels-region(te)
"Remove the vowels"
(interactive "sTe:")
(replace-regexp-in-string "[aeiouAEIOU]" "" te)
)
I hilite some text and then call remove-vowels-in-region.
A first step would be sufficient to get me on my way : I'm not a lisp
programmer but am learning a little.
