How do I search for the selected (with v and y) string? I usually search with /, but I cannot paste the selected string after /.
回答1:
In insert mode you can use CTRL-R to insert the contents of Vim registers. By default, copied text gets put in the unnamed register ", so to insert that text you would type <C-R>" in insert mode. The search prompt uses Command-line mode which has its own
CTRL-R that works almost identically to the one in Insert mode.
So if I just yanked the text foo, typing /<C-R>" would search for the text foo once I press enter.

I have this mapping defined in my vimrc, it maps * to defining the search pattern as what is currently highlighted (escaping all potential dangerous characters, and converting a space in what is highlighted to any sequence of spaces)
xnoremap * :<C-U>let old_reg=getreg('"')|let old_regtype=getregtype('"')<CR>gvy/<C-R><C-R>=substitute(substitute(escape(@", '/\.*$^~['), '\s\+', '\\s\\+', 'g'), '\_s\+', '\\_s*', 'g')<CR><CR>gV:call setreg('"', old_reg, old_regtype)<CR>:let v:searchforward=1<CR>
In order to use it, start visual mode with v, and then highlight what you want to search and press * not y.
Of course you can map # to search backwards (exactly the same except that v:searchforward should be set to 0.

:set hls
:vmap * y:let @/ = @"<CR>
set hls(hight light search)v=>hjkl(select something)- press
*, copy selected text to reg" - set content of reg
/as" - press

If you only care about searches, you can use the cheat method I use. Yank a word via v or y+w, then issue the command
:%s//XYZ/gc
This will search for the last searched word. Then when you find it, it will ask for confirmation to replace with XYZ, and all you have to do is hit q to quit.
