Top row keys
The top row keys are the ten keys found above the home row keys on a QWERTY US keyboard. The top row keys include the Q, W, E, R, and T keys for the left hand and Y, U, I, O, and P keys for the right hand. In the picture below, the hands are on the home row keys and the top row keys are above the home row keys.
As you may have already noticed, the first six top row keys on a QWERTY keyboard are "QWERTY".
With a Dvorak keyboard the top row keys are the ?, <, >, P, and Y keys with the left hand and the F, G, C, R, and L keys with the right hand.
