the tab key, works with the traverseListener.
For your problem with the mouse, I think that you can set:
e.doIt = false;
if you want to stop the event after you have highlighted the text, or into the mouseUp event catching.

yes, its by default. But if you want to cange that order, you have to create a collection with the widgets and "force" the next.
