and below are the most used short cuts:
SUPER+SHIFT+DRAG LEFT MOUSE = draw fire
SUPER+SHIFT+C = clear fire
CTRL+ALT+DRAG LEFT MOUSE = rotate cube
CTRL+ALT+LEFT ARROW = rotate cube
CTRL+ALT+DOWN ARROW = flat desktop
SHIFT+ALT+UP=initiate window picker

SUPER+TAB=flip switcher or ring switcher depending on which is enabled.
ALT+F7=initiate 'move windows'
SHIFT+F9=water effect

For Grouping and Tabbing:
SUPER+S=Select Single Window
SUPER+T=Tab Group
SUPER+Left=Change Left Tab
SUPER+Right=Change Right Tab
SUPER+G=Group Windows
SUPER+U=Ungroup Windows
SUPER+R=Remove Group Window
SUPER+C=Close Group
SUPER+X=Ignore Group
hold the super button then select the windows you want to group and then hit super+g

also You can add new shortcuts.. all that you have to do is just you can select one of the plugin(double click on it) and in actions tab of the plugin, under bindings you can change the shortcuts. You can even add a screen edge as a binding so that when you move your mouse cursor to screen edge(say top left) compiz will execute the particular action. It goes really nice with expo plugin. have a great time with compiz fusion!
(the one with windows logo on it (in some keyboards along with windows logo "start" is printed)
This is the super key..
