<a href=#thisIsWhereIWantItToGo>link to that part of the page</a>
<a name=thisIsWhereIWantItToGo>destination part of page</a>
something like that
sorry - that was same page. different page is similar but with # directly after destination url
so <a href=otherpage.html#thisIsWhereIWantItToGo> go there </a>
