Erik Darling reminds you to check out the properties of execution plan elements:
I read a lot of posts about query plans, and I rarely see people bring up the properties tab.
And I get it. The F4 button is right next to the F5 button. If you hit the wrong one, you might ruin everything.
But hear me out, dear reader. I care about you. I want your query plan reading experience to be better.
Erik provides sound advice here.
