Question: There is not an `Edit | Preferences` option. How do I get the files to display in a list view with details, and not as icons?

Answer: 
In 12.04 and 12.10 (under the default Unity desktop environment), **hold down the** `Alt` **key for just a second**, and you'll see the options for Edit->Preferences and the rest (top left of the screen). 

Maximization will also let you see the pull-down menus, but isn't necessary. The handy shortcut to maximize your application or window is `Ctrl`+`Super`+`Up` ("Up" is the "Up Arrow" key). The same combo but with the down arrow reverses the maximization effect. 

In Unity, hold down the Super or Windows key to see shortcuts. 

**It's generally easiest**, though, to use `Ctrl`+`2` to see a list view, and `Ctrl`+`1` to go back to icons.
Open your file manager then move your mouse to the left of the top panel
and select 'View' then 'List' (near the bottom) or try CTRL+2.
