I believe "?" is used to indicate that the preceding character can appear once or not at all, so that would be zero or one times.

I’m a bit confused. I thought "?" was for one or more times, but that might be "!"?

I think "?" means zero or one times, but I'm not completely sure. It feels like it could also be related to other quantifiers.
