Vim - Capture strings on Search and use on Replace

I have a css selector such as:

#page-site-index .toolbar .items {

How do I capture the ".toolbar .items" part and use it on Replace part of Vim S&R, so this selector can turn into:

#page-site-index .toolbar .items, #page-site-login .toolbar .items {

Something like:

%s:/#page-site-index \(.toolbar .items\)/#page-site-index (the captured string), #page-site-login (the captured string)/g

Btw, I'm using the terminal version of Vim.

Use \1... See the wiki here: http://vim.wikia.com/wiki/Search_and_replace

More explicitly: 

%s:/#page-site-index \(.toolbar .items\)/#page-site-index \1, #page-site-login \1/g

You've already grouped the interesting parts of the regular expression via \(...\) in your attempt. To refer to these captured submatches inside the replacement part, use \1, \2, etc., where the number refers to the first (opened) capture group, from left to right. There's also \0 == & for the entire matched text. See :help /\1 for more information.

try this command in your vim:

%s/\v#(page-site-index )(\.toolbar \.items)/&, #page-site-login \2/g

you could also use \zs, \ze and without grouping:

%s/#page-site-index \zs\.toolbar \.items\ze/&, #page-site-login &/g

keep golfing, if the text is just like what you gave in question, you could:

%s/#page-site-index \zs[^{]*\ze /&, #page-site-login &/g

First type the : the get into command mode. Then issue the following command:

%s/#page-site-index .toolbar .items/#page-site-index .toolbar, #page-site-login
.toolbar .items/

Don't care about the formatting, its because of the stackoverflow markdown parser....
