Did you check the documentation?

Re-use steps using the auto-complete mechanism

I already checked the documentation. However, it is kept very short. 

Our keywords don't differ between testing environments, but between parts/areas of the test object. And these are different between projects.

I understand.

Let me try to assist.

1. Define categories that are relevant for your case, by parts/areas of the app under test.

2. Create at least one BDD feature for each of those categories, set the two fields (auto-complete category & Contributes to auto-complete).

3. go to another BDD feature with the same category (but not necessarily contributing to the auto-complete)

4. Press ctrl+space

Probably, I should explain my question with an example:

Project A may want to use categories "natural person", "legal person", "address data" and "contacts".

Projekt B would like to differ keywords by "customer", "address data", "order", "article", "inventory", "shipment" and "bill". 

That would be 10 categories in one list and a category "address data" used by both projects because of Shared Space level.

Challenge One: A test analyst working for Project A has to know, that keywords concerning customers are found in categories "natural person" and "legal person". Category "customers" shouldn't be selected in this project.

Challenge Two: Keywords in "address data" may be similar, but not all the same. So test analyst adding a new test has to know, which keywords from this category are fitting its test object.

Challenge Three: There may be more projects and categories per project resulting in an even longer list. I may add projekt name to category, but do I get a well-arranged list and good usability?

I wonder, how other users implemented this feature? Which categories do you use?
