Specifying What to Display in the History Pane
As described in History Pane, the History pane initially displays information about the alert currently selected in the Alert file. However, you can switch from this view to one that displays information about all alerts in the Alert file.
1. If the Alert file is not already open, then open it. You open this file in the same way as any other file.
2. Select Filter > Select History by Alert Selection.
Repeating this step switches between the two views.
When a checkmark appears to the left of this command, the History pane displays information about the active alert.
When no checkmark appears to the left of this command, the History pane displays information about all alerts.
