Fountain Mode features internal pagination. This is achieved by periodically calculating where page breaks occur in the whole buffer and applying pagination properties to the text. When the text is changed enough to invalidate these properties they are recalculated.
An important factor in calculating pagination is the page size. This
is the target page size. Valid options are letter or a4.
This option specifies how many lines fit on each of the page sizes.
This option controls whether pagination properties will automatically
be updated when using paging command, e.g.
fountain-forward-page.
Maximum change in page characters before invalidating pagination. Set this to a lower value to get more accurate pagination, high if you find the updates annoying.
Whether pagination will break pages within sentences, or only at sentence ends.
Hook run after calling fountain-insert-page-break.
You can optionally show the current page and total page count in the
mode line by enabling which-function-mode, See (emacs)Which
Function. This will display something like this:
[Page 31 of 90]
Bound to C-c C-p, return both the current page and the total page count of the current buffer.
You can also navigate by page number. See Navigation.
