Hebrew Used With Ubuntu?

[Xurxo Fernandez]

        i would like to generaly write in English, but switch to Hebrew
        when I need it.

I cannot tell you about hebrew in particular, but Linux is quite
flexible regarding languages. You want your computer in french, just
download the language pack. Japanese, hebrew... you name it. Switching
from an english desktop to a hebrew one is just as easy as closing the
session and changing the default language. I have my computer in
japanese and I use SCIM to switch from english input to japanese. If I
want to run an application in english (i.e. gimp) I write LANG=en and
the name of the application in the terminal.
