The info section of the menu compiles information about the current stack, and puts it into the Global HEXInfo. Choosing the "report" menuItem allows you to choose whether to save the information to a file, or to display it in a window on screen. The command opens a window for each of the four report types, or updates it, if it is already visible.
The same applies to the "Objects with Scripts" item of the ScriptTools window, which compiles a list of all stack objects with scripts and then puts them into HEXInfo, again, all that has been said already of the 'report' menu item applies to the results of this handler.
If there is a window for the appropriate report already open then you can still choose to save the current info to the file by holding down the option key as you choose the menu item.
