It tries to compile automatically when you have made any changes and click on the world.

Find the underlined world in the class editor and hover the mouse over it. Also (or), you must create a subclass of World.

Show the codes you have created (see the 'Posting code? read this!' link below the 'Post a reply' input box to check out to show your codes). Show all subclasses of World and Actor (and any other class you may have added).

The 'isKeyDown' method is in the 'Greenfoot' class -- not the 'greenfoot' class (which there is not one of).

Change 'greenfoot' in the code above to 'Greenfoot'.

If it doesn't compile, there should be parts red underlined to indicate errors.

You have shown part of a subclass of Actor. I asked for you to show ALL codes you have created (meaning entire class codes of ALL subclasses of World and Actor. I do not know if you even have a subclass of World, which is required, yet.
