You can copy a Notify to the clipboard for pasting elsewhere along the animation, or inside different Animation Sequences.
To copy a Notify:
Right-click on the Notify and select Copy.
Right-click and select the desired Paste option:
Paste - Paste the notify at the current location of the time slider.
Paste at Original Time - Pastes the notify at the same time as when it was copied.
You can also perform actions for multiple notifies by Shift + Left-clicking on a notify to add it to a selection or Ctrl + Left-clicking to toggle a notify from a selection.
You can drag the selection around and it will remain within the notify panel while keeping snapping intact.
When multiple notifies are copied, by Right-clicking in the timeline to bring up the context menu, you will notice additional paste options.
Paste Multiple Relative: Paste at the mouse cursor retaining relative spacing between notifies regardless of animation length. This means that the notify group should look like it is spaced the same as before the copy; even if the animation is shorter or longer.
Paste Multiple Absolute: Paste at the mouse cursor retaining absolute spacing. The notifies will retain their exact time spacing meaning that they will fire at exactly the same intervals but the group is not scaled to shorter or longer animations.
Paste at Original Time: Puts all of the nodes exactly where they were when they were copied.
Any paste operation that would put any of the notifies off the right edge of the track will still succeed but the notifies will be clamped into the track.
Pasting at the mouse cursor uses the most top-left point in the selection as a reference point for placing the nodes.
Pasting a group that would pass below the bottom of the notify panel will add as many tracks as necessary to contain the group automatically.
