I am looking in the manual for two isearch functionalities that maybe
are already implemented, but I don't find them. Else maybe it is not
so complex to do in elisp (at least for my config) And you could suggest
a right way to implement it.

1) isearch-yank-thing-at-point, this should be similar to
isearch-yank-word, but if the cursor is in the middle of a word
it may insert the whole word not just the rest of the current word.

(swiper provides this with M-n)

The closest to this that I'm aware of is
isearch-forward-symbol-at-point, bound to 'M-s .' by default.

2) In "transient-mark-mode" if the region is active before C-s, the
initial input could be the text in the region. Is it there a way to
enable that behavior?

An alternative for this is a command that yanks the region's text in the
minibuffer when isearch is active so we could bind it in the isearch-map
(for example to M-f).

Are some of these already implemented?

I'm not familiar with any built-in versions of the rest of the
functionality you describe, but I'm no expert.  If it is indeed not
currently present, I for one would welcome such additions.



Hi Basil:

I just made a small change in isearch.el to enable region text auto
insertion in transient-mark-mode. (patch attached)

I did it as simple as I could. So please if you (or any anyone) could
give a look and correct/improve/expose corner cases, or suggest a better
implementation will be very nice.

I don't have corner cases right now, but I just started testing it.

So any correction/suggestion/recommendation is very appreciated.

Thanks in advance,
