You can undo changes that you make in the Topic Editor. If you made changes to frames other than the current frame, the Topic Editor navigates to the frame where the change was made. For example, if you add custom text to the bubble for three different frames, and then undo all three additions, the Topic Editor navigates back to each frame where the bubble text is being undone.
If you are using sound in the Topic Editor, Undo undoes frame by frame recordings. The Topic Editor updates the frame view, frame structure, and waveform while undoing.
Undo does not affect operations with attachments in the Frame Link Properties window.
You can also redo actions that you have undone. Like Undo, if the action you are redoing occurs on another frame, the Topic Editor navigates to that frame.
