What are the rules for the usage of this construct?
For example, suppose you've written a StackExchange answer, and later you decided edit it so that your proposed solution handles an additional case. If you wanted to say "I've edited my answer to include the case..." would you follow that with when, where or of? What are the grammatical conditions?
I know it must have something to do with the following part of your sentence being "situational", "descriptive", etc. but I'm not sure.
