罗技鼠标LUA程序：数字键位控制鼠标移动

"下面是一个简单的罗技鼠标LUA程序，当按下数字键位1234时，鼠标会移动一小段距离。\n\nlua\nfunction OnEvent(event, arg)\n if event == \"G_PRESSED\" and arg == 4 then\n PressKey(\"lshift\")\n Sleep(30)\n MoveMouseRelative(50, 0)\n Sleep(30)\n ReleaseKey(\"lshift\")\n elseif event == \"MOUSE_BUTTON_PRESSED\" and arg == 4 then\n PressMouseButton(1)\n elseif event == \"MOUSE_BUTTON_RELEASED\" and arg == 4 then\n ReleaseMouseButton(1)\n end\nend\n\n\n以上代码中，当按下鼠标G4键位时，会先按下左Shift键，然后移动鼠标相对位置为(50, 0)，最后释放左Shift键。这一过程持续时间为30毫秒。当按下鼠标G4键位时，会按下鼠标左键，释放时则释放鼠标左键。"
