If you have both KDE and GNOME installed on your system, you can use applications from the other environment. For example, you can use the GNOME email and personal information management suite, Evolution, while you are working in KDE. You can access GNOME applications by clicking the Start Application button (the 'K' icon at the bottom of the screen), then choosing Programs from the menu.
