It's an associative array, so you need the exact index as a decimal with
no leading zeros; ranges and reverse indices don't work.

% print ${(t)history}
association-readonly-hide-hideval-special

But you can fake something like that above up:


local -a myhist=() indices=({$((HISTCMD-5))..$((HISTCMD-1))})
integer ind
for ind in $indices; do
  myhist+=(${history[$ind]})
done
