- Paste
- Pastes the contents of the paste buffer to the event display. Keyboard equivalent: +V.
The result of copying and then pasting multiple items depends on what you copied:
- If you copied multiple actions, pasting adds them all to a single new event, even if they originally came from different events.
- Copying multiple events or wires pastes them exactly as copied.
- If you copied a combination of actions and events, pasting creates a new event for each group of actions from a single event. For example, if you highlight event A, some actions from event B, and some actions from event C, copying and then pasting would add three events: a copy of event A, a second event with the actions from event B, and a third event with the actions from event C.
- Paste Instanced
- Pastes the contents of the paste buffer to the event display, making instances of any pasted actions and their originals.
For the results of pasting multiple copied items, see Paste, above.

. Deleting an event also deletes all of its actions.
