What is does the pipe {'|'} mean in a configmap?-CodePudding

My quest is basically:

What is does the pipe {'|'} mean in a configmap? Code Sample: Taken from: https://kubernetes.io/docs/concepts/configuration/configmap/

apiVersion: v1
kind: ConfigMap
metadata:
  name: game-demo
data:
  # property-like keys; each key maps to a simple value
  player_initial_lives: "3"
  ui_properties_file_name: "user-interface.properties"

  # file-like keys
  game.properties: |   # <--- Here
    enemy.types=aliens,monsters
    player.maximum-lives=5    
  user-interface.properties: | # <--- Here
    color.good=purple
    color.bad=yellow
    allow.textmode=true

This seems a bit of trivial but what does it mean and what is its purpose. Any special use cases.

Thank You for any clarification!

It's a multiline string. See https://yaml-multiline.info/ for examples
