Reply To: Lifting pinky up during hagba

I think it’s because they’re pointing at the Torah when they say the pasuk of “And this is the Torah…”. But it’s considered disrespectful to point at a Torah with your index finger so they use the pinky instead. However, I am not aware of any source that brings the custom of pointing during Hagba and I have seen many talmidei chachamim who never do this.
