Puts user input focus on the current element.
public void Focus()
Setting the focus on an element both gives that element focus and makes it the active element; for example, the element that has focus will be returned by the ActiveElement property of HtmlDocument.
Any key strokes entered by a user after Focus has been called will be sent to that element.
