question: how do I show more results?

I know I can increase the number of results shown by setting the MCFLY_RESULTS environment variable. However, I am okay with the default number of results but sometimes I want to increase the number.

For example, in fzf it shows ten results by default but if I want to see more I can scroll past the last result. In mcfly, I cannot scroll past the last result.

How do I tell mcfly I want to see more results for this specific invocation?
