Add ability to send key events easily from Browser...

[the-t-in-rtf]

Browser should provide a convenience function to submit arbitrary key input.

In this issue, it was suggested that authors who need this synthesize their own events. This is not acceptable for a modern testing framework, specifically because of the need for accessibility testing. It should be easy to send tab keys, arrow keys, and enter keys to confirm that screen reader users and users without a mouse can operate an interface.

It would also help with simple use cases like confirming that hitting enter in a query field generates search results.
