Act Mover
Act (also called "Event") delete, move and copy functions are provided by a dialog, because each event can have many associated details.

In this example, four events are being moved within the Earthquake arena. Any number of acts can be selected for any of these functions, whether a range or noncontiguous. LeftClick act letters to select or deselect them.
If the Delete function is chosen, the Accept button will always be available and no destination arena is shown. If a Move or Copy function is chosen, the Accept button is visible only when an equal number of source and destination fields are chosen. The moved or copied acts are mapped one for one into the destination acts. If the move or copy is within one arena, the destination events may not be the same as sending events. EFGH cannot copy or move into HIJK, for instance.
As with the Cascade panel, the mouse flyover lets you see what the event is. "InCascades" refers to the effect-flow from other acts. Any number of other acts might alter the enabled-state of Earthquake/E above, for example. You can move the text data out of Earthquake/E while leaving these incoming effects alone. "InScripts" refers to the effect-flow from scripts. "TextAndNote" refers to the text data in the act. "Details" refers to the triggering thresholds, default state, odds, etc. "OutCascades" and "OutScripts" are the effects this act has on other acts or arenas.
