Are you permitted on Shabbat to open the microwave oven to remove food that you forgot to put on the Shabbat table. (by opening the microwave door, the light inside turns on) If the answer is no, are you permitted to open the microwave with your foot ( using a shinuee). This is obviously a case where removing the food from the microwave is not a life or death situation.

It is in any case forbidden since putting on the light even with a "shinui" would still be an issur d'rabanan- a rabbinical prohibition.
