title: what is the shortcut for "replace all" in pycharm
body: <p>I want to hit a shortkey and replace all in Pycharm. 
  After I hit ctrl+R, I key in text to search and text as replacement.
  I need to click "Replace" / " Replace all".
  I currently move my hand to mouse and click the button, but I do it many times in a day. Anyone knows what is the shortkey? Thanks.</p>
  
  <p>Here's the official document shows how to find and replace by click the button
