Undo and redo

Scene and layer edits can be undone and redone: Edit ▸ Undo and Edit ▸ Redo, or ⌘Z and ⌘⇧Z (Ctrl+Z and Ctrl+Shift+Z on Windows and Linux). Every app has them.

What can be undone

• moving, resizing, rotating and cropping a layer, and its aspect and opacity (dragging the opacity slider is one step);
• a layer’s portrait-layout placement;
• showing or hiding and locking or unlocking a layer;
• a layer’s effects and fades;
• moving a layer up or down the stack (see Layers);
• renaming a scene and moving it in the scene list;
• removing a scene: Undo puts it back in its place in the scene list with its layers, its transition and its place in scene automation, and a layer it shared with another scene is linked again. A scene that was on Program or Preview comes back in Preview (in Studio Mode) or as the selected scene; Undo never changes what is on Program. Redo removes it again;
• removing a layer (the trash button, Delete or Backspace): Undo puts it back in its place in the stack with its position, size, opacity, effects, visibility and lock, and the selection is put back. A media file or RTMP Server layer is opened again (a media file from its start, paused). Removing a linked layer from one scene removes only that scene’s link, and Undo brings the link back, not a copy;
• copying or pasting a layer into a scene: Undo removes the copy;
• linking a layer into another scene: Undo removes the link;
• unlinking a layer, and linking a layer to the existing layer of the same name: each is one step;
• a scene’s transition and its transition override (see Transitions);
• a text layer’s text edited from the layer list.

A linked layer’s edit is undone in every scene that shows it.

What cannot be undone

Adding a scene or a new layer, switching the Program or Preview scene, changing the canvas size, and resetting a scene’s portrait layout are not recorded.
