1. middle-ring-little finger combination
2. index-middle-ring finger combination
I've found that it's easier for me to use the middle-ring-little finger combo, as I can hold onto my indicator more easily with my thumb and index finger.
Please note that I didn't ask for the "right" or "proper" method, just your preferred method.
Oh, if there is another option that I didn't mention, please share it.
