Let's look at it a different way. If whenever your user is
somewhere in your application and they click the Help button, if
the developer simply programs things so that the help opens at the
default topic, then the help is not context sensitive. If they
program things so that the help opens to either the screen or field
the user is working in, then the help is context sensitive, it is
aware of what the user needs help on. As I indicated before, you
can either produce separate topics for each field or you can put
them all into one topic for the whole screen. As far as you are
concerned when authoring, those topics are the same as topics
describing how to use the help for example. You are writing them in
the same way but with the intention the developer can call them.
Only if called in that way do they become context sensitive.
In some older programs you could click in a field and click a
question mark top right of the window. A small rectangle would
appear with a small amount of text describing the field or telling
you what to do. I think it is used less and less.now.
I have indicated two ways of writing field help. Beyond that
maybe look at some of the applications you use.
I hope this is more helpful.
