You will be able to collapse only cells that have some hierarchical relationship. The most obvious is when using sections, subsections, etc., in a notebook. (Think of them as headers, sub-headers, etc.) For instance, go to menu Cell -> Style and choose Section. Enter some text in this cell, and below create a new cell with, say, a plot command. Evaluate it. You should see some bold text, the plot command and a graphic. Now select all the cell with Ctrl + A, and then Ctrl + { Now you should see only the title in bold. > By the way my Windows system menu says Ctrl+' is the > keyboard shortcut - nothing about Alt+Shift. I stand corrected. Of course your are right: the keyboard shortcuts start with the control key Ctrl and not Alt (same thing in version 6). > I've looked all through the help system and have found > nothing about this subject.

I believe that a good source of information and tutorial is section "1.3.5 Notebooks as Documents" of The Mathematica Book. It is available in the online help or at http://documents.wolfram.com/mathematica/book/section-1.3.5 HTH, Jean-Marc
