Ubuntu 12.04 keyboard commands

[Lenny]

Hi,
Can anyone help me get started on a Ubuntu 12.04 live CD?
I need it right now to work on a USB drive, so I need to get into the menus, 
like system, preferences, to get to gParted.
No matter what I do, I cannot get off of the desktop.
I am used to earlier versions of Ubuntu.
I searched the web and have found no list of keyboard commands.
Thanks.

Glenn
