You already got lots of good answers. Here's

HTH,
This sounds brilliant Jean-Rene, I put it into my .vimrc, but it doesn't
seem to work, I did notice that between the if and else there are
which just act as comments as they are on newlines, didn't know if this
was just my text wrapping, so I tried putting them on the line above,
both with a space between or not, didn't know if that might be cause but
that didn't seem to help either. Sorry I may be missing something
obvious, but I'd like to get this to work as it seems very useful.
I was selecting text in visual mode, then pressing / or ? and I just get
the normal action of pressing / or ?
Thanks,
Rob.

I think the original included raw CR characters in the two :execute
lines. Both are intended to end with ^M (which is how they appeared
in my copy of Jean-Rene's note). I think your e-mail client broke the
lines, leading to syntax errors.

Sorry, I should have known that wouldn't come out
right. There's a literal newline between the
quotes. You can enter it by pressing
CTRL-VCTRL-M.
Here's that section of code with the literal
newline entered as two separate characters:
if a:direction == 'b'
execute normal ? . l:pattern . ^M
else
execute normal / . l:pattern . ^M
endif
I was selecting text in visual mode, then
pressing / or ? and I just get the normal action

Well you could do it with / and ? but I like
to keep their behavior intact as it is useful to
extend the visual region.
I remapped * and # instead, as shown in these
lines:
vnoremap silent * :call VisualSearch('f')CR
vnoremap silent # :call VisualSearch('b')CR
I prefer that because these don't have any special
meaning in visual mode and it ties in nicely with
the search next/previous word function they have
in normal mode.

Everything seems to work fine now, except the searched for items aren't
highlighted like they normally are when I search, is there a simple
reason or am I just asking for too much, sorry I can't sort this out
myself, but I don't understand the function well enough to see a
possilbe reason, the only thing I could think of that might cause it
would be this in my .vimrc
Clears search highlighting by just hitting a return.
The BS clears the command line.
(From Zdenek Sekera [EMAIL PROTECTED] on the vim list.)
I added the final cr to restore the standard behaviour of
cr to go to the next line and the mz and `z to return the cursor to its
precommand position
:nnoremap CR mz:nohlsearchCR/BSCR`z
However, if this were interfering it would clear the command line as
well and I don't see that so it can't be the cause.
Thanks,
Rob.

I agree with what you say below completely, I just didn't express myself
clearly enough in the paragraph above, I was just telling you the
actions I had performed and it appears I should have been pressing * or
# not / or ? as I originally thought, but the lack of the literal
newline was causing it not to work too.
Well you could do it with / and ? but I like
to keep their behavior intact as it is useful to

:set hls?
This is quite strange, it is set, i.e.
:set hls?
returns
hlsearch
If I use your visual selection when I first launch gvim, then it works
with the highlighting. If I then use Enter to clear the highlighting
according to this line in my .vimrc that I gave before:
:nnoremap CR mz:nohlsearchCR/BSCR`z
then the highlighting is no longer displayed as is expected.
If I then do
:set hls?
again, I get again:
hlsearch
but if I use your visual selection tool again then this time I get no
highlighting. Of course if I set hls again using :set hls then it works
fine again until I press enter.
So what I was thinking was just to add a :set hls at the start of your
function, then it should alway highlight the searched for items, however
I tried variations on including it but no nothing about scripting so
they didn't work, can you tell me how I should add it? I tried the below
but it didn't work.
Thanks,
Rob.

I have learned a lot from this thread!
I changed the function slightly (see below) because I also
didn't understand the missing ^M was causing my problem.
I like to use * and # for searching for a string in highlight
mode, then I press F10 to turn off highlighting. However,
pressing F10 with nohls highlights the word under the cursor
without searching for it, which was is a modification of some
comments at the bottom of vimtip #1.
Between this thread and the discussions in vimtip #1 I now
have the following which works really *really* nicely:
begin
disabled initially since it distracts me
set nohlsearch
in normal mode, make * highlight the search string
nnoremap silent * *:set hlsCR
nnoremap silent # #:set hlsCR
in visual mode, use highlighted selection for search pattern
vnoremap silent * :call VisualSearch('f')CR:set hlsCR
vnoremap silent # :call VisualSearch('b')CR:set hlsCR
function! VisualSearch(direction)
let l:saved_reg = @
execute normal! vgvy
let l:pattern = escape(@, '\/.*$^~[]')
let l:pattern = substitute(l:pattern, \n$, , )
let @/ = l:pattern
let @ = l:saved_reg
if a:direction == 'f'
normal n
else
normal N
endif
endfunc
map F10 to toggle the highlight search mode
if hlsearch is on then simply turn it off
if hlsearch is off then highlight word under cursor only
nnoremap silent F10 :call SetSearchReg()CR:set invhlsCR
function! SetSearchReg()
if hlsearch == 0
let @/ = expand('cword')
endif
endfunc
my mind/fingers think of F10 as highlight search mode
so make visual mode F10 and ShiftF10 work like * and #
vnoremap silent F10 :call VisualSearch('f')CR:set hlsCR
vnoremap silent S-F10 :call VisualSearch('b')CR:set hlsCR

Subject: search visual block
Is it possible to search for a string by selecting that
string in visual mode? Meaning, if I highlight something,
and then want to search for that thing which is highlighted
in the rest of the doc?
otherwise, is there a way to copy that string so that I can
later put it into the :/ command?
I know you have had lots of different reponses on this thread.
This is what I keep in my vimrc, which doesn't use a function.
Simply highlight the text and hit * or #, just like you would for a given
work in normal mode.

Visually select text, then search for it
if version = 602
Here are two enhanced versions of these mappings which use VIM 6.2's
getregtype() function to determine whether the unnamed register
contains
a characterwise, linewise or blockwise selection. After the search has
been executed, the register *and* its type can then be restored with
setreg().
vnoremap silent * :C-U
\let old_reg=getreg('')bar
\let old_regmode=getregtype('')cr
\gvy/C-RC-R=substitute(substitute(
\escape(@, '\\/.*$^~[]' ), \n$, , ),
\\n, '\\_[[:return:]]', g)crcr
\:call setreg('', old_reg, old_regmode)cr
vnoremap silent # :C-U
\let old_reg=getreg('')bar
\let old_regmode=getregtype('')cr
\gvy?C-RC-R=substitute(substitute(
\escape(@, '\\/.*$^~[]' ), \n$, , ),
\\n, '\\_[[:return:]]', g)crcr
\:call setreg('', old_reg, old_regmode)cr
else
If you use both VIM 6.2 and older versions these mappings
should be defined depending on the current version.
vnoremap silent * :C-Ulet old_reg=@cr
\gvy/C-RC-R=substitute(substitute(
\escape(@, '\\/.*$^~[]' ), \n$, , ),
\\n, '\\_[[:return:]]', g)crcr

RE: search visual block
From :help visual-operators Note that the :vmap command can be used to specifically map keys in Visual mode. For example, if you would like the / command not to extend the Visual area, but instead take the highlighted text and search for that: :vmap / y/C-RCR I would suggest not using the default yank register (it annoys me when things clear it without warning me!) so try this instead (which uses the 'q' register instead): :vmap / qy/C-RqCR Then whenever you press / with something highlighted in visual mode, it will get searched for! Hope that helps!
