The callable *settings.PAGE_LIST_CALLABLE* can be used to customize
how the pages are displayed. The callable takes the current page number
and the total number of pages, and must return a sequence of page
numbers that will be displayed. The sequence can contain other values:
- *'previous'*: will display the previous page in that position;
- *'next'*: will display the next page in that position;
- *'first'*: will display the first page as an arrow;
- *'last'*: will display the last page as an arrow;
- *None*: a separator will be displayed in that position.
Here is an example of custom calable that displays the previous page,
then the first page, then a separator, then the current page, and
finally the last page::
