The area in the upper half is where you enter the query you want to run. The lower half is where the results are displayed. We’ll see an example of this in action later in this post.
Just above the query area is a toolbar. The Run button will execute the query you’ve entered. Note too, you can use the keyboard command SHIFT+ENTER to run a query. I’m a keyboard guy, so this is what I use most often to run queries, which you’ll see if you take either of my KQL courses on Pluralsight (I’ve linked to them in the Conclusion of this post).
Read on for a walkthrough of the product. Robert also mentions his Pluralsight course, which I thoroughly enjoyed and used as research materials for a talk I put together.
