1. A method of operating a system that includes: a display; a user input device for receiving signals from a user; and a data processor that receives input signals from the user input device and provides output signals to the display; the output signals causing the display to present images that include display objects; each of a set of the display objects being perceptible as a distinct, coherent set of display features; the method comprising: operating the data processor to provide first output signals to the display; the first output signals causing the display to present a first workspace containing a first subset of the set of display objects; the display objects of the first subset being perceptible as having spatial positions relative to each other when presented by the display; the first subset including a first display object that is perceptible as a tool that augments a user's capabilities; while the display is presenting the first workspace, receiving a switch signal sequence from the user input device; and in response to the switch signal sequence, operating the data processor to provide second output signals to the display; the second output signals causing the display to cease presenting the first workspace and begin to present a second workspace containing a second subset of the set of display objects; the display objects of the second subset being perceptible as having spatial positions relative to each other when presented by the display; the second subset including a second display object that is perceptible as a tool that augments a user's capabilities; the first and second subsets of display objects being different from each other so that the first and second workspaces are perceptible as different workspaces; the second display object being perceptible as the same tool as the first display object.
