Yes, when I'm talking about something to a group of people, I like questions, they let me know where I need to be more in depth and where I an keep glossing. However, a good answer from a presenter is in fact "I will cover that in a bit (a few slides, or whatever)", and part of being a good questioner is temporarily accepting "I don't understand this one thing" and working around it. Sometimes it turns out that a bit of understanding falls out of understanding other, surrounding bits of knowledge first. Being a good questioner/learning isn't just about understanding everything instantly or when you first notice you don't understand, but rather noting the places where you need clarification, and paying attention for things that fill in that knowledge.
