Thank you very much for all the answers ! Great !

More generally now : Again I have a list of list but with more
"dimensions" Something like that :

data={{x1,y1,z1,f1,g1,h1},{x2,y2,z2,f2,g2,h2},{x3,y3,z3,f3,g3,h3},...
{xn,yn,zn,fn,gn,hn}}

And let's say I wanna, for the sake of the example, add 10 to all the
y's i.e. I want

{{x1,y1+10,z1,f1,g1,h1},{x2,y2+10,z2,f2,g2,h2},{x3,y3+10,z3,f3,g3,h3},...
{xn,yn+10,zn,fn,gn,hn}}

According to all your suggestions, I could do

{#1,#2+10,#3,#4,#5,#6}& @@@ data

Right ? Isn't there another simpler way (imagine instead of 6 elements
(x,y,z,f,g,h), I have 100 !)
