Print associative array keys on separate lines in Bash? [duplicate]

Question

The answer on that other one %s\n' "${myarray[@]}" when used on an associative array prints the values only while I'm looking for the keys.

declare -r -A myarray=(
   [a]=1
   [b]=2
   [c]=3
   [d]=4
)

Would like to have:

a
b
c
d

So just:

printf "%s\n" "${!myarray[@]}"
