2D hit and focus cursor (Shift+O)

Normally, 2D hit selects the target object and the cursor remains at the original location. This command selects the object and moves the cursor to the selected object.

In the picture below, the active view is an XZ view, and the cursor is located outside the model. Using normal 2D hit to select the duct part keeps the cursor at the original location, but using 2D hit and focus cursor moves the cursor forward to the selected object.
