The Buddha Garden on "How Do I Display Navigation from Parent PAGES to Subcategory PAGES???"

I understand that PAGES can have a PARENT page. In essence, a PAGE can be in a subcategory of another page. Right?

How can I AUTOMATICALLY display links from a parent PAGE to it's subcategory PAGES?

For example: Say I create a PAGE called "Widgets"

Then I create a PAGE called "Blue Widgets" and I select the Widgets PAGE as the PARENT of the Blue Widgets page.

Will their be links built automatically from the Widgets PAGE to the Blue Widgets PAGE???

Or will I have to hard code them in?

Or will I need to use a Widget?

Any help is appreciated.
