This management screen lets you see a paged list of Events. The page size is set by the mgmt_batch_size property (see the Properties tab).
Each item has a check box that you can use to select Events for deletion. Check the boxes for Events you wish to delete and then click the Delete button.
If you click on the Event title you can edit the Event; if you click on a Date/Time entry then you can edit the date and/or time of an Event.
Multiple date/times are supported. To add or delete dates for an Event, click on the title, then click either the "Updates/Reviews/Dates" tab or the "date and update/review management" link on the Edit an Event form. From there you can add new dates (and update/review objects as well).
The Open Filter Form link reopens the page with a filter dialog where you can select date ranges as well as filter by Subject or Reviewed status (the latter for Moderated sites only).
Moderated sites also have an Open unreviewed Updates and Reviews list link. This reopens the page with a list of unreviewed Updates and Reviews. Click on the ID to edit an item, click on Parent Title to edit the parent of the item (helpful to determine the context).
