what is a template in Intellij?

I created a project, package, script in Intellij.

There is not a green arrow on the menu bar that I usually see.

Right clicking on the main class is not showing the choice  to run in the drop down.

I use the menu bar and click on run.  

A small rectangle appears.  It says run in the title and Edit configurations.  I  don't know what this is.  I click on configurations and get to the screen that I attached to this post.

Thanks,

Kevin

I tried quite hard to get to the state where you are but with no success:
Used IDE is IntelliJ 2023.1.
Projects were "Empty Project" and "Java Project"

Can you describe in more details:

What version of IntelliJ you are using

What kind of Project type you created? Empty, Java, Kotlin, ....

How did you create the package inside the project?

Roland,

I don't remember if this was when I was on version 20 or after I downgraded to version 17.  
I must have entitled this thread "what is a template in Intellij"but I don't know why I did that.  Perhaps there was an error message on the screen saying something about a template.  
Recently I have been placing the class right under the Project which might not be a good idea but so far the Head First Book has not started talking about the packages yet.
My friend in India did a zoom call with me and after fixing things in my code we got the green run arrow to return.  I wish I recorded the issue with screen shots and wrote down how he fixed this.

I got up to about page 139 in my book and think I am moving along too fast.   I keep forgetting details. It is as if my short term memory is so clogged up that it cant transfer to long term.  
I'm going on a vacation for a week and will take a break from the book.   I need time to absorb what I have been learning.  I have a few more posts on Code ranch to answer and then I am stopping.

Thanks,

Kevin
