Notebooks and Documents 145Manipulating NotebooksCells as Mathematica ExpressionsLike other objects in Mathematica, the cells in a notebook, and in fact the whole notebook itself,are all ultimately represented as Mathematica expressions. With the standard notebook frontend, you can use the command Show Expression to see the text of the Mathematica expressionthat corresponds to any particular cell.Show Expression menu item toggle between displayed form and underlying Mathemat -ica expressionCtrl+* or Ctrl+8 (between existingcells)Handling Cell expressions in the notebook front end.put up a dialog box to allow input of a cell in Mathematicaexpression formHere is a cell displayed in its usual way in the front end.Here is the underlying Mathematica expression that corresponds to the cell.Cell@contents,"style"DCell@contents,"style",optionsDCell@contents,"style 1 ","style 2 ",…,optionsDa cell with a specific stylea cell with additional options specifieda cell with several stylesMathematica expressions corresponding to cells in notebooks.Within a given notebook, there is always a collection of styles that can be used to determinethe appearance and behavior of cells. Typically the styles are named so as to reflect what rolecells which have them will play in the notebook.
