Enhancing fold manipulation techniques

Folding is an effective means to overcome the inherent problem associated with displaying a large information space on a small computer screen. This technique has been successfully deployed in a variety of application domains, ranging from text editors and spreadsheets to information spaces with a tree structure hierarchy. However, this paper argues that the folding facilities currently available in many commercial products could be improved. It further proposes a number of features which may be used to enhance folding to enrich the human-computer interaction
