Set your anchor name in the options page.
Typical use case: a big picture in the header you don’t want people 
to be bothered with every time they click on an internal link. But 
you still want that beautiful picture to be there.

wp-permamod

Very simple plugin that adds an anchor to page and post permalinks, which can point to an existant anchor in your template.

This plugin adds a smooth scroll effect motion to anchor links on the same page. 
You can apply the effect to all posts/pages or certain posts/pages and adjust scroll speed.
The links are bound by the id attribute.
For the source/origin element, link to the target like so, with a href attribute of the target id <code><a href="#example"></a></code>
For the target element, you give it a corresponding id attribute like so – <code><h2 id="example">the target</h2></code>
