Steps:
1. Load a document
2. In developer console, listen to selectstart events, e.g.
document.addEventListener("selectstart", function(evt) {
  console.log('Selection started ', evt); 
}, false);
3. Start AccProbe and find an AccessibleText, expand it
4. Use AccessibleText.addSelection to set the selection

Notice that selectstart is not fired (it is fired when selection occurs via mouse).

Why this is useful: for complex web apps that need to respond to selections being set by an AT, e.g. via cursor routing on a Braille display.
