To help you write DRQL syntax, autocomplete keeps track of information that you have recently typed and tries to anticipate what you want to type next. Autocomplete displays possible options for each statement identifier and topic, topic property, response, and response parameter names.
For example, when you start writing a rule, WHEN displays in an autocomplete list. After you select WHEN from the list, a list of possible topics displays in an autocomplete list, as shown in the following image:
Select an item, and that item is placed in the rule syntax. Autocomplete continues to list possible selections for each item.
