It's just like $hash{foo}, except you have multiple keys. 
@hash{qw( foo bar )} = (1, 2);

is basically the same as 
$hash{foo} = 1;
$hash{bar} = 2;

(I said "basically" because there is a difference. The former uses a list assignment while the latter uses two scalar assignments. List assignments don't return the same as scalar assignments. See Mini-Tutorial: Scalar vs List Assignment Operator)
