Creating a Named step in groovy - jenkins

Question

I'm trying to learn groovy for my pipeline set-up and I'm stuck on something realy basic, but I don't know where to start looking to solve my issue.
What I'm trying to do is basicly create a stage with multiple Named steps. Underneath I've posted a basic example of what I'm trying to do, what would be the 'go to way' to do this.(this just creates a folder with a zipped file inside it).
Sidenote: This code currently throws the error
WorkflowScript: 23: Expecting "interface jenkins.tasks.SimpleBuildStep" but got Mkdir
pipeline {
agent any
stages {
stage('Zipfile'){
steps{
step('Mkdir'){
sh 'mkdir LocalDir'
}
step('Touch File'){
sh '''cd LocalDir
touch File
cd ..'''
}
step('Zip'){
sh '''cd LocalDir
zip File.zip File
cd ..'''
}
}
}
}
}

Answer 1

I think I have to disappoint you. You can't name a step. The official documentation doesn't mention such a thing.
From the official documentation:
steps
The steps section defines a series of one or more steps to be
executed in a given stage directive.
Required: Yes
Parameters: None
Allowed: Inside each stage block.

Answer 2

I think i found what the question was expecting... I should have added named stages with steps in them
pipeline {
agent any
stages {
stage('Zipfile'){
stages{
stage('mkdir'){
steps{
sh 'mkdir LocalDir'
}
}
stage('Touch File'){
steps{
sh '''cd LocalDir
touch File
cd ..'''
}
}
stage('Zip'){
steps{
sh '''cd LocalDir
zip File.zip File
cd ..'''
}
}
}
}
}
}
