This function can be used to help user input a modification of some text.

 function change { bash -c "read -ei \"$1\" temp && echo \$temp" }

What is idiomatic zsh way to do something similar?

With the vared builtin.

change () {
  local temp=$1
  vared temp
  print -lr -- $temp
}

And if you want to use the string entered by the user later in your script, it's just

temp='initial value'
vared temp
