１．There are a total of 52 keys.
２．The "Shift" key in the upper left corner changes color when tapped, indicating that the "Shift" function is enabled. Tap it again to restore the color and disable the "Shift" function. The function of each key changes depending on whether or not the "Shift" function is enabled. The functions of the keys are described below, starting from the bottom left.
