Type: Feature Addition

===Credit===
**Mark Kasper** and **GmBowen** **(main credit for the idea and initial code)**
**AHerdOfTurtles** (for helping me see that this is a cool idea)
**[[JsnX | Jason Tourtelotte]]** (major refinement to the code -- almost a complete rewrite)
----
=== Description ===

This modification adds the ability to show an index listing of pages that start with a certain letter. There is also an alphabetical heading at the top of each listing. Just click a letter to see pages that start with that letter.

For example:

Usage:

%%
{{pageindex letter="d"}}
%%

Outcome:

{{pageindex letter="d"}}

=== Code ===
