Opens a pop-up explorer where you can select one or several parameters to which you can override. Use Ctrl+click to select
more than one parameter. Click anywhere outside of the property editor to end.
The property editor will display a new parameter for every parameter you selected from the pop-up menu. Depending on the selected
property, the new parameter line will appear with a check box or a connection icon for connecting another shader to an object's
parameter without nullifying any of the object's original properties. For example, an Enable parameter will show a checkbox
when overridden, but a color parameter will allow you to connect a texture to drive it.
