This is the PC keyboard,  showing  the  unshifted  and  ALT
values for each key.  With most linux software, the ALT key
shifts to the upper half of the ANSI 8859-1 character  set.
The  second of each pair of rows is the shifted characters.
That is, each above block of four characters represents the
four characters you get from one key, laid out as:

     plain  ALT
     Shift  ALT+Shift

If these don't display correctly, then you are  looking  at
them  with  something  that  doesn't  handle the ISO 8859-1
character set properly.
