I don't understand what's supposed to be especially intuitive about this? It's an alphabetic list of fallacies - how do I "lookup" one if not by just scrolling

I don't understand what's supposed to be especially intuitive about this? It's an alphabetic list of fallacies - how do I "lookup" one if not by just scrolling down the list? I have no idea what the symbols below the search bar mean and was surprised that the "i" button doesn't give me more information about the site or showed help but instead just apparently switched between descriptions and synonyms.
