title: How do I disable NVDA's arrow key navigation
body: <p>I have a collection of buttons inside a div, with some javascript to move focus between them in response to arrow key events.</p>
  
  <p>When I test this with NVDA/Firefox/Windows it seems that NVDA overrides my arrow key handler and moves focus according to its own rules. This is a problem because my widget is highly customisable, dynamic, and responsive - so the rules for moving focus around are quite complex.</p>
  
  <p>Neither Voiceover nor ChromeVox has this behaviour.</p>
  
  <p>I noticed that adding role="gridcell" to each button seems to fix this, but I'd prefer not to do that because it means screenreaders won't treat my buttons as buttons. I also really don't want to change the html structure (e.g. wrapping each button in another element) unless it's absolutely necessary.</p>
  
  <p>Is there a way (e.g. aria or proprietary attribute) to tell NVDA not to apply its own arrow key behaviour to the buttons?</p>
