Shifted Keys

Each key has three functions: one printed on its face, a left–shifted function (Green), and a right–shifted function (Purple). The shifted function names are printed in green and purple above each key. Press the appropriate shift key ({ or ) before pressing the key for the desired function. For example, to turn the calculator off, press and release the shift key, then press .
