ankulua keyevent bluestacks

is it possible to keyevent a key to click the "Trim memory" function? I have tried changing the shortcut to a key that could send keyevent but nothing works. I have attached image below if possible to somehow click that feature through ankulua. Currently using bluestacks pie 64-bit (5.9.300.1014 P64)
