Terminal Special Bindings in MacOS Terminal app

I really wanted to be able to use Option + Left or Option + Right to navigate through words in terminal input. Option + Delete to delete a word is also really handy.

The Terminal App has this feature of using the Option key as a "Meta" key. This unlocks all of those great shortcuts ! This article highlights the shortcuts that are unlocked like this : https://www.shell-tips.com/mac/meta-key/

However this breaks some useful basic shortcuts, like all those used to write unicode characters. The pipe character for instance, printed by Command + Option + L cannot be used anymore when this option is enabled.

Your Kubernetes control-plane has initialized successfully!

To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

You should now deploy a Pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
