Input action not showing up

Hey all,
New to blueprint and unreal. I am following this tutorial:

When I get to the point at 1:32 where he is saying to right click and select the key-mapped action, I don’t even get an option to see it.
See screenshot: Imgur: The magic of the Internet

I am in the event graph and everything. Please help, sorry if this is a beginner question

Hi, what is the parent class (you can see it on top right corner) of your blueprint? The keyboard input context option is not available on all blueprint types. For example, you won’t find in the context menu for Game Mode or HUD blueprints, but will be able to use it in all blueprints derived from the Actor class.
