Panasonic micro timer vs standing time vs delay start, button order question

Standing time has not been used much in my kitchen, my mother taught me that for foods like pizza, lasagna, or anything that contained frozen ingredients it was a good idea to allow for an additional 1 minute standing time. It makes a huge difference in the texture of the food. No relation to the buttons though.
 
Sensor cook models lockout the duration of cooking since the sensor controls the cooking time. Standing time can still be entered though, simply push the Time/Clock button and set the desired duration prior to pressing start. At least this is how it works on my NN-SN966.

Thanks for the answer about sensor cook, did not know this would work. Will give it a try with the leftovers I made tonight.
