How to view Adapter docs in Designer?

I remember back to the time of Developer, when I opened an adapter service and click help menu item, it would show the corresponding help doc based on what kind of adapter service I’m watching. It’s usually some HTML pages under pub folder of adapter package. My question is can we do the same thing in Designer?

I may be wrong, but I think the Developer help will bring you to the help page for that service type, not really adapter type.

in designer, the help list all under help content, better organized.

Yes as Tong Wang mentioned with in the Designer under Help -->Help Contents is the only option to browse all the related topics → SoftwareAG Designer Guides (High level - but this does not gives you deep dive info though)
