Re: convection/microwave manuel
Welcome to the forum, Velma!
The word "convection" just means 'hot air' (and no politician jokes, please!)
The normal microwave doesn't brown stuff like cookies or green bean casseroles. So, they added heating elements to the microwave and a fan to blow the hot air around inside. The convection part will work along with the microwave part.
The biggest change from a normal oven is the cooking times. There are recipe books specially published for microwave / convection ovens, but a little trial-and-error goes a long way, too.
