You want (i):

  % echo $jobstates[(i)*]
  1 2 ...

With k and K the *keys* stored in the assoc (as opposed to the *exp*
given in the subscript) are used as patterns:

  % typeset -A type
  % type=('[a-zA-Z]' alpha '[0-9]' digit '[^a-zA-Z0-9]' other)
  % echo $type[(k)x] $type[(k)4] $type[(k).]
  alpha digit other
