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)
           (goto-char begin)
           (error "not found"))
           (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.
