The combination toaster oven and toaster appliance of claim 3 wherein the arm is pivotably mounted to the housing and pivoting the arm from the toast position to the oven position causes the sliding linkage to move, the at least one pivoting linkage to pivot and the slot cover to move from the retracted position to the extended position covering the at least one slot. 5. The combination toaster oven and toaster appliance of claim 2 further comprising: a selector switch mounted in the housing, the arm actuating the selector switch in the oven position to close an upper branch of an electric circuit of the appliance, the arm actuating the selector switch to open the upper branch in the toast position. 6. The combination toaster oven and toaster appliance of claim 1 further comprising: a carriage movably mounted in the housing, the carriage being movable between a toast position and a loading position, the carriage being biased toward the loading position, the carriage actuating a toast switch in the toast position to commence a timed toasting cycle in a toast mode wherein the heating element is powered to heat the food cavity. 7. The combination toaster oven and toaster appliance of claim 1 wherein the heating element is comprised of a first pair of upper heating tubes and a second pair of lower heating tubes, the upper heating tubes associated with a pair of reflector shields that reflect radiation heat energy from the upper heating tubes toward a central portion of the food cavity, the lower heating tubes associated with a pair of shield boards that are positioned between the lower heating tubes and the central portion of the food cavity, the shield boards including holes therein to permit radiation heat energy from the lower heating tubes to travel toward the central portion of the food cavity, the shield boards also generally deflecting relatively large pieces of foodstuff from coming into direct contact with the lower heating tubes. 8. A combination toaster oven and toaster appliance for cooking and heating foodstuff, the combination toaster oven and toaster appliance comprising: a housing having a top wall, a front wall and defining a food cavity therein; a slot in the top wall; a slot cover movable between an extended position covering the slot and a retracted position exposing the slot; a toaster oven opening in the front wall providing access to the food cavity; and an arm movably mounted to and extending from the housing, the arm movable between an oven position and a toast position, the arm being linked to the slot cover such that the slot cover is in the extended position when the arm is in the oven position and the slot cover is in the retracted position when the arm is in the toast position. 9. The combination toaster oven and toaster appliance of claim 8 wherein the arm is pivotally mounted to the housing, the housing including a front wall having a slit therein, the arm including a handle portion that extends out of the housing through the slit. 10. The combination toaster oven and toaster appliance of claim 8 further comprising: a carriage movably mounted to the housing, the carriage being movable between a loading position and a toast position, the slot cover generally preventing insertion of the foodstuff into the food cavity and onto the carriage in the extended position and generally permitting insertion of the foodstuff into the food cavity for placement on the carriage in the retracted position. 11. A control system for a combination toaster oven and toaster appliance comprising: a housing having a top wall and a front wall, the housing defining a food cavity; a heating element for heating the food cavity; a slot in the top wall; a toaster oven opening in the front wall and a door movably mounted to the front wall to selectively close and expose the toaster oven opening; a slot cover movably mounted to the housing, the slot cover being movable between an extended position covering the slot and a retracted position exposing the slot; an arm movably mounted to the housing, the arm movable between an oven position and a toast position, the slot cover being in the extended position when the arm is in the oven position; a carriage in alignment with the slot and being movable between a loading position and a toast position; a selector switch mounted to the housing proximate the arm, the selector switch actuating the appliance to a toast mode when the arm is in the toast position and actuating the appliance to an oven mode when the arm is in the oven position. 12. The control system of claim 11 wherein the selector switch is a microswitch. 13. The control system of claim 11 further comprising: a toast switch mounted to the housing, the toast switch being actuated when the carriage is in the toast position, power flowing through the toast switch to the heating element when the appliance is in the toast mode and an electronic toast control is running a timed toasting cycle for heating the food cavity. 14. The control system of claim 13 further comprising: a timing knob mounted to the housing, the timing knob being in communication with the electronic toast control and being rotatable to modify a toasting time defining an amount of time power is provided to the heating element, power being cut to the heating element at a conclusion of the toasting time. 15.
