title: Ace Editor - Change CTRL+H keybinding
body: <p>I'm working on an implementation of <em>Ace Editor</em> and <kbd>Ctrl</kbd>+<kbd>F</kbd> works great for the built-in "Find" dialog, however I'm trying to find a way to change out the <kbd>Ctrl</kbd>+<kbd>H</kbd> for <kbd>Ctrl</kbd>+<kbd>R</kbd> and prevent default behavior.</p>
  
  <p>I've looked over docs and forums about working with the keybindings but I can't identify what method is being called to instantiate the 'replace' dialog or how to overwrite it.</p>
