M4400-UK keyboard can someone take a pic for me please

my keyboard does not have Gr on it lol...it just says Alt...wot does Gr stand for anyway

ok i googled it, it stands for graph...but yea my keyboard dosent have any Gr label on it

 

On UK (maybe other European keyboards) the Right-Alt is AltGr, which as you say is for graphics, way back in DOS the *only* extra character you got from it was Alt-Gr plus the [`¬] key got you a "¦" character (as opposed to the "|" character)

Now with recent windows versions it is used to get other symbols like € and accents á é ú í ó in combination with letters.
