[LBo] Questions after reinstallation

[Rafi Gabzu]

Hi,
After reinstall Debian (long story )  I found that GNOME is much better and
nicer than KDE so I decided to stay with it , but now I do not know few
things :
1. How do I set keyboard combination to toggle between two keyboard layout ?
2. I'm looking for more nice English fonts than the current, which are
recommended and how to install  ?
3. Where can I see (graphical) the system properties like Kernel version,
distribution, CPU etc. ?

General question : How do I overcome the " key " alarms I keep getting when
performing update ?

Thanks,
Rafi
