Indicating jump links UI wireframe

I hope this is the right forum.

I am drawing out a wireframe for a web developer to follow, indicating the layout of a website. I want to draw this out by hand, using the best practices/layout that a Wordpress web developer would find most useful.

I have a homepage which is long-scrolling. Some elements on the top navigation bar menu take the user through to a separate page, but some of the elements are jump links to areas on the homepage further down (alternatively viewed by scrolling down).

How should I indicate this on my wireframe (this is hand-drawn, just a simplified sketch)? I don't want to cause confusion just going with my gut and start drawing out lines and boxes that indicate something different, in common wireframe practice, to what I am trying to illustrate.

Thank you.
