title: How to recall search pattern when writing replace regex pattern in Vim?
body: <p>Here's the scenario: I've got a big file filled with all sorts of eclectic rubbish that I want to regex. I fiddle around and come up with a perfect search pattern by using the <kbd>/</kbd> command and seeing what it highlights.</p>
  
  <p>Now I want to use that pattern to replace with. So, I start typing <kbd>:%s/</kbd> and I cannot recall what the pattern was. Is there some magical keyboard command that will pull in my last search pattern here? If I'm writing a particularly complex regex, I have even opened up a new MacVim window, typed the regex from the first window into a buffer there, then typed it back into the Vim window when writing the replace pattern. There has got to be a better way of doing so.</p>
