The Events view offers most of the features that are available in both the Navigate view and the Legacy Events view. Similar to the Navigate view, there is a view into meta keys and meta values for logs, endpoints, and packets. Like the Legacy Events view, an events list shows events listed in the order by time, and you can view the raw event, related metadata, and a reconstruction of an event. The Event reconstruction has some helpful cues to identify points of interest. See Reconstructing and Analyzing Events.
The following figure shows the initial Events view with some examples of queries and information about keyboard and mouse interaction. This figure depicts the initial view.
This figure show the examples provided in Version 11.4, which has two modes for creating queries.
