Just realized I can just use "..." to go back two directories! Is this a zsh feature? (lemmy.ca)

I accidentally discovered that both "cd ..." and "..." work, and moreover, I can add more dots to go back further! I'm using zsh on iTerm2 on macOS. I'm pretty sure this isn't a cd feature. Is this specific to zsh or iTerm2? Are there other cool features I just never knew existed??

I'm so excited about an extra dot right now.

I have a function called up. I do up X where X is the number of directories I want to go up.

up() {
  if [[ $# -eq 0 ]]; then
    cd ..
    return 0
  fi
  local path i
  for (( i=0; i < $1; i++ )); do
    path+=../
  done
  cd "$path"
}

EDIT: Don't know if it's just me but if you see < it should be the less than character.
