title: VsCode extension. How to select a tree view item on right click
body: <p>I am writitng a VsCode extension. When the user Right Clicks on an item in the tree view, he gets the popup command, whose actions apply to the previously selected item. In VsCode itself, this isn't the case. RightCliking on New File, for instance, adds a file to the currently highlighted folder (Not the selected one). How can I replicate this behavior in my extensions?</p>
