What is a tool, "way of doing things" or maybe even ability, that you often use and not many people think is even an option?

What is something you think more people should know about, that you rarely see but is a valid option to use or do, that many people just dont know is a possibility?

I think its hard to explain so I give you an example: So it is often the case, that a lot of good, valid information and or sources are behind paywalls or only available in expensive books. Normal Libraries rarely have that. A lot of people dont know, that a lot of university libraries have access to those things. You can register at most university libraries like a normal library and get access to books, and papers that costs a lot of money otherwise, even without working there or being a student.

Once registered it is often even possible to access a lot of scientific magazines or books by just using a vpn to the library.

I think its a skill and tool that would help a lot of people to stay factual in arguments and not require a use of unreliable information that basically is an opinion instead of a source for a valid fact.
