Memorizing CLI commands and typing/editing them over and over can be very time consuming.

Use k9s for example. Let's say you want to determine where the value of an environment variable is coming from.

1. 'kubectl get deploy -n example' (find the name of the deployment in question)

2. 'kubectl describe deploy example-app -n example' (determine where the value for the env var is coming from)

3. 'kubectl get cm example-app-config -n example -o yaml' (check the value of the referenced key in the config map)

This is a very basic example but you can see where it lead to slow debugging that is made even slower by its propensity to typos and the need to look up command syntax. Once you get comfy in a well designed TUI, you can fly through this process in 10 seconds.
