How to mark and search text in less keystrokes ?

How to mark and search text in less keystrokes ?

[Christiano Farina Haesbaert]

I saw my boss doing the following in vi the other day and it seemed
quite useful, suppose:

You are editing a buffer, and your pointer is at the word
myfunc(a,b),

How can I search for the occurences of the word myfunc at the same
buffer AND mark my position where I was, so I can iterate through the
results and get back to my original spot at any time.

For now I'm using C^s and "typing" the word ( I know it's lame ), and
when I want to get back I loop thought until I'm back at the original
spot.

Please if I didn't make myself clear I can try to explain better.

Another thing, is it possible to iterate through all function calls of
myfunc in a directory ?
Currently I gave a grep, that tries to match the patter of myfunc
call, but is kinda clumsy.

obs: As you can see I'm not an Emacs wizard, it's just my second
month.

Try C-s and then C-w to "pull" words into the search string.

Start with

  C-s C-w

and then to move use

  C-s

To go back use C-g

Have you tested lgrep and rgrep in Emacs?

[Parker, Matthew]

With point just before a word

C-s C-w does a search on that word

Repeated C-s will step through matches

C-g will quit search and return point to where you started

Return/Enter will stop search and leave point at current match

Thanks a lot Lennart and Mathias, that was exactly what I wanted.

Not yet, I was using normal grep in emacs, I will take a look into it.

After searching, use `C-x C-x' to get back to where the searching started. This
works because Isearch sets the mark before searching.

One reply:

> To go back use C-g

Another reply, saying the same thing:

> C-g will quit search and return point to where you started

But C-g takes you back to the beginning only if you never exited Isearch (e.g.
with RET).

I thought the OP meant that he exited search and later wanted to get back to the
search start. For that, just use `C-x C-x'.

Actually you are right, that's what I meant, I figured that C-g would
only work after my reply, C-x C-x is what I need indeed.

Thanks a lot.

Argh I mean, C-g would not work as I wanted.

But that will activate the mark in transient-mark-mode.
C-u C-SPC will just jump to the previous mark (and pop it off the mark ring).

And?

I use `transient-mark-mode' (via `delete-selection-mode), and I still typically
use `C-x C-x', not `C-u C-SPC', in this context. `C-g' deactivates the mark, if
you don't want it to remain active - so `C-x C-x C-g'.

But `C-x C-x' lets you go back and forth between the search hit and the origin.
To get back to the search hit after you've done `C-u C-SPC', you must cycle all
the way around the `mark-ring' (or use a numeric arg).

Anyway, glad you mentioned `C-u C-SPC' here. It's good to be aware of multiple
possibilities and what each does. The important thing here is that `C-s' sets
the mark before it sets off on its quest for search hits.
