Mathematica Tutorial: Notebooks And Documents - Wolfram Research

180 Notebooks and DocumentsMathematica makes it possible to specify a different evaluator for each cell in a notebook. Butmost often, the Evaluator option is set only at the notebook or global level, typically using theKernel Configuration Options menu item in the front end.The option CellAutoOverwrite is typically set to True for styles that represent Mathematicaoutput. Doing this means that when you reevaluate a particular piece of input, Mathematica willautomatically delete the output that was previously generated from that input, and will overwriteit with new output.The option GeneratedCell is set whenever a cell is generated by an external request to thefront end rather than by an interactive operation within the front end. Thus, for example, anycell obtained as an output or side effect from a kernel evaluation will haveGeneratedCell -> True. Cells generated by low-level functions designed to manipulate notebooksdirectly, such as NotebookWrite and NotebookApply, do not have the GeneratedCelloption set.optiontypical defaultvaluePageBreakAbove Automatic whether to put a page break just above aparticular cellPageBreakWithin Automatic whether to allow a page break within aparticular cellPageBreakBelow Automatic whether to put a page break just below aparticular cellGroupPageBreakWithin Automatic whether to allow a page break within aparticular group of cellsOptions for controlling page breaks when cells are printed.When you display a notebook on the screen, you can scroll continuously through it. But if youprint the notebook out, you have to decide where page breaks will occur. A setting ofAutomatic for a page break option tells Mathematica to make a page break if necessary; Truespecifies that a page break should always be made, while False specifies that it should neverbe.Page breaks set using the PageBreakAbove and PageBreakBelow options also determine thebreaks between slides in a slide show. When creating a slide show, you will typically use a cellwith a special named style to determine where each slide begins. This named style will haveone of the page-breaking options set on it.Additional functionality related to this tutorial has been introduced in subsequent versionsof Mathematica.
