Awesome @runofthemill! I have one for Bedrock/normal WordPress that also functions as a shortcut to that directory, but also a quick way to install/activate plugins from Packagist and WPackagist. These are from my old dotfiles that haven't ported over yet.

bedrock() {
  startDir="$(pwd)"
  sitePath="$(dirname `dirname $(wp config path)`)"

  cd $sitePath

  if [ -z "$1" ]; then
    return false
  elif [ $# -eq 2 ]; then
    composer require $1/${2} && wp plugin activate ${2}
    cd $startDir
  else
    composer require wpackagist-plugin/$1 && wp plugin activate $1
    cd $startDir
  fi

} 

bedrock-dev() {
  startDir="$(pwd)"
  sitePath="$(dirname `dirname $(wp config path)`)"

  cd $sitePath

  if [ $# -eq 2 ]; then
    composer require --dev $1/${2} && wp plugin activate ${2}
  else
    composer require --dev wpackagist-plugin/$1 && wp plugin activate $1
  fi

  cd $startDir
}

wpp() {
  startDir="$(pwd)"
  sitePath="$(dirname `wp config path`)"

  cd $sitePath

  if [ -z "$1" ]; then
    return false
  elif [ $# -eq 2 ]; then
    composer require $1/${2} && wp plugin activate ${2}
    cd $startDir
  else
    composer require wpackagist-plugin/$1 && wp plugin activate $1
    cd $startDir
  fi
} 

wpp-dev() {
  startDir="$(pwd)"
  sitePath="$(dirname `wp config path`)"

  cd $sitePath

  if [ -z "$1" ]; then
    return false
  elif [ $# -eq 2 ]; then
    composer require --dev $1/${2} && wp plugin activate ${2}
    cd $startDir
  else
    composer require --dev wpackagist-plugin/$1 && wp plugin activate $1
    cd $startDir
  fi
} 

I've been using these to jump around lately:
