Animation editing apparatus for editing animation data, comprising data storage means, processing means, visual display means and a manually responsive input device configured to allow a user to indicate a selected point on the visual display means.The visual display means displays an image representing a simulated three-dimensional world-space including a plurality of simulated objects, and the manually responsive input device provides an input signal indicating a location within the image corresponding to one of the simulated objects. In response to receiving the input signal, the processing means identifies the selected simulated object, and retrieves data from the data storage means of one or more related items related to the selected simulated object within a defined degree of relationship. The visual display means displays labels identifying the selected simulated object and the related items only.
