I’m glad you listed the manual example. Usually when people are solving problems, they’re not asking the kind of super targeted question in you second example. Instead it’s an exploration. You read and target the next concept you need to understand. And if you do have this specific question, you want the surrounding context because you’ll likely have more questions after the first.

So what people do is collecting documentations. Give them a glance (or at least the TOC), the start the process to understand the concepts. Sure you can ask the escape code for setting a terminal title, but will it says that not all terminals support that code? Or that piping does not strip out escape codes? That’s the kind of gotchas you can learn from proper manuals.
