Eventually, the ability to use Help would be ideal, yes. But the wiki-literacy and google-skill that some of us have from our decades of exposure can be a barrier at the very onset of Paratext use for those whose literacy is primarily linear. Would it be great if every translator developed wiki-literacy and google-skill? Sure. But it needn’t be a prerequisite to learning how to use Paratext effectively.
The example you give, ‘project notes’, is a good one. When I search for project notes and anon421222’t include the quotes (google-skill), I get 50+ hits. Which of these should I start with? The first hit is “Introduction to Project Notes”; a good start. But the next hit is “How should I set the options on the Tools menu?”. Someone with wiki-literacy might readily identify this as not particularly important to read right now when you’re just getting started with project notes. Someone with linear literacy would be more likely to read the next item, then the next, then the next. It can be easy to get lost in a sea of new information without someone identifying for you which bits are important for you at which stage.
Now, the list at the end of “Introduction to Project Notes” is great; it will take you to the foundational information that you need. It’s even organized in a helpful linear fashion (kudos!). Let’s say I click the first item, “How do I insert a project note?”. Once I finish reading that article, I would go to the list at the end of that note for my next bit of information. But the list here is different. The first link takes you back to “Introduction…”, where you could access the original, fuller list of related topics. Or the reader could say to themselves that they have already seen the first one, they will now click the second list item (wiki-literacy), “How do I add a comment to note?”. So now they have access to that new information and can apply it. But what if they wanted to go back to the “Introduction…” right away? They’d have to use the back button (wiki-literacy) to see what they were looking at before. And, doing that, they would no longer be able to see the other helpful and related information, something that they can do if it has been presented in a linear format.
I agree that many would benefit from just such a “quick find” guide as you are recommending (good idea!). Still, I know that there are also many who would benefit from having the wiki/google barrier minimized at the onset of Paratext exposure. It would be pretty easy to pull a quick guide out the Table of Contents of my proposed Word doc. Both/and rather than either/or, eh?
