for the first time - Excuse me for being rude ;-)

1. While you move the mouse-pointer over the menus in the GIS-Manager,
the "real" name of each module is displayed on the bottom of the window

2. For each module there is (or should be) a GUI. On the bottom of it
you can see the actual command that will be executed. It is a good
practise to "watch" the changes of the command while changing options,
names, flags or whatever in a modules GUI.

Take for example r.report:

In the GIS-Manager: Raster > Reports and statistics > Sum area by map
and category

(watch "real" name of pointed menu line on the bottom: r.report)

Now in the "r.report" GUI: Play around with flags, buttons etc and watch
the command syntax changing on the bottom. After executing a command
with the GUI one can repeat the same command by using the copy button on
the bottom left corner: copy the command and paste it in GRASS' shell,

GRASS is an excellent learning tool.
