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.

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 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
