Dear All,
I would like to be able to select some text with C-space and then look
for it inside the buffer.
I found some functions online which I modified to get:
;; a function to search the selected text
(defun my-search-forward (begin end)
(interactive (list (point) (mark)))
(let ((text (filter-buffer-substring begin end nil t)))
(goto-char (max begin end))
(let ((found-pos (search-forward text nil t)))
(if (not found-pos)
(progn
(goto-char begin)
(error "not found"))
(progn
(goto-char found-pos)
(set-mark (- found-pos (length text))))))))
(define-key global-map [(control q )] 'my-search-forward)
It is almost there but not yet...
If I highlight some text, I can look for it with C-q, but once at the
end of the buffer, it stops searching (whereas I would like it to search
from the beginning of the buffer).
If then I move to the beginning of the buffer, not everything above my
last position is selected, but also the function loses memory of what I
was looking for...
Anybody can give me some help? Apologies if there is already and emacs
command for that, but my online search was not fruitful.
Cheers
Lorenzo

You can also use isearch-forward like that:
put the point at begining of text and then hit C-s C-w C-w C-w ....
until you are at the end of text and then C-s C-s ...etc...

Many thanks, I cut and pasted a few lines and noticed the improvement (I
selected the snippet by Jury Linkow in the site you suggested). But it
seems to me this mainly deals with finding a single long word in the
text by placing the cursor on it.
What if instead I want to find e.g. two words on the spot?
Cheers
Lorenzo

Or C-y to search for text between point and end of line, instead of taking
words one by one. Repeating C-y takes one more line at a time.
Or, kill or save the text to the kill ring and yank it for search with M-y
(i.e., after having pressed C-s).
Once you defined some text to search for, you can edit it, moving point to the
minibuffer with M-e.
See here: *info* (emacs)Isearch Yank (chapter 20.1.6)
Even more if you see the documentation of `isearch-forward'.
