--Now send the keys as you like, e.g.,

result1, result2, result3 = sendKey(tvip, "KEY_TOOLS")

log(result1, result2, result3)

os.sleep(1)

result1, result2, result3 = sendKey(tvip, "KEY_RIGHT")

log(result1, result2, result3)

os.sleep(1)

result1, result2, result3 = sendKey(tvip, "KEY_DOWN")

log(result1, result2, result3)

os.sleep(1)

result1, result2, result3 = sendKey(tvip, "KEY_RIGHT")

log(result1, result2, result3)
