# Notepad++ highlight occurrences of selected text

I know that I can double click a word and Notepad++ will highlight all instances of that word within the document. My question is not about this.

Does anyone know of a plug-in or setting which will allow me to select as many characters as I please and highlight all occurrences of those characters?

Given the following text file:

$hey_you = 'hey you';$hey_me = 'hey me';
$hey_we = 'hey we';  With my cursor I wish to select $hey_ and have the 3 \$hey_s highlighted.

Also, if the scroll-bar could behave like Google Chrome's with yellow markings then that would be a huge bonus, too.
