title: Key bindings for navigating through selection regions
body: <p>When you press <kbd>Ctrl</kbd>+<kbd>F</kbd>, enter some search query and click on <code>Find All</code> (or hit <kbd>Alt</kbd>+<kbd>Enter</kbd>), Sublime Text 3 will find and select all occurrences of searched term found in current document. It will even count then, writing <code>X selection regions</code> in status bar.</p>
  
  <p>I'd like to add a functionality, where pressing <kbd>Alt</kbd>+<kbd>Left Arrow</kbd> moves cursor to previous selected region, while pressing <kbd>Alt</kbd>+<kbd>Right Arrow</kbd> moves it to the next selected region.</p>
  
  <p>I know how to modify Sublime Text 3's key bindings and add own keyboard shortcut, but I have no experience with selection regions in ST3 API, so I don't even know, where to start.</p>
  
  <p>Can someone help here?</p>
