Pages, Units, & Navigation

Many pages of the website can be considered part of a sequence: that one should be read before or after another as in a book. The majority of pages of this type can be found in the EXPLORE section.

"CD Player"-like buttons are often found in the upper and lower right-hand corners of pages. These buttons help navigate from page to page and unit to unit.

Go back one unit, skipping in a threaded circle backwards through the list of units/sections at the same level.	Go back one page. If the first or top page of a unit, this backs up to the very last page of the unit.	Go up one level. This is either the first page of the unit (if in the middle of a unit) or to the encapsulating section.	Go forward one page. If the last page in a unit, returns to the first or top page of the unit.	Go forward one unit, skipping in a threaded circle fowards through the list of units/sections at the same level.

All "CD Player" buttons follow a sequence that can be thought of as a great circle. Pressing the "page-forward" button repeatedly cycles through the pages eventually returning to the starting point. Pressing the "unit-forward" button repeated cycles through the units eventually returning to the starting point. The same principle applies to the "page-backward" and "unit-backward" buttons.

The "up" button breaks out of this cycle. At the lowest level, the up button points to the first page of the current unit. At any other level, it points to the super-section containing the current unit/section.
