A computing device (10) for capturing designated data from one or more graphic applications (60) comprising a screen area (16) for viewing one or more graphic functions (111) wherein each function (111) is manipulated with a plurality of shortcut keys (75) or a cursor pad (24) communicably linked to the screen area (16). A first applications (60) with a screen interface (100) for the user is provided within the device (10) having graphing capabilities for manipulating the graphs (111) on the screen area (16). A cursor (64), cursor pad (24) and shortcut keys (75) are used to trace data along the graph (111) and capture the points to a stack area (84) where they are stored for future use by a second application (90, 92). The second application (90, 92) gives the user the ability to further study and analyze the data. Alternatively, shortcut keys (75) can be used to automate the transfer from the first application (60) to the second application (90, 92).

Device and method for collecting data from graphed images

Calculator having a keyboard in which one or more keys have labels created by a display and subject to changing interactively as the user desires. Typically, advanced scientific-programmable calculators may have too many functions to be adequately included on the keys of the keyboard associated therewith. In such calculators, certain functions require a plurality of keys to be actuated in order to be performed. Thus, such keyboards tend to be cluttered an confusing to the user. Thus, a keyboard is proposed having a small number of keys labeled with different functional labels as the user proceeds through a menu or tree structure containing all the desired functions. Keys in a certain group of keys on the keyboard are thereby subject to redefinition or relabeling so as to provide a variety of functions.
