Looking for How-To document

I just made a simple circuit (Vsource=1, diode=1n4148, .op) and the hover-Ctrl gave me the power display for about 1 second. Has the .savepowers been defaulted to on? Is there a way to make the power display last as long as the Ctrl key is held down? Is there a way to view all the option defaults in a circuit?

Thanks,
Carl
