Guide: InDesign bullets for arbitrary prefix strings

It is occasionally useful to set an arbitrary text prefix at the paragraph style level. One such example is for a table of contents where entries are formatted as follows:

Page # -- Title of entry

InDesign's auto-generated table of contents can reproduce this entire example with the exception of the prefixed word Page followed by a space.

We can add the prefix by creating a custom bullet character in the Bullets and Numbering section of the paragraph style options.

1. Under Bullet Character choose Add.
2. Select the very top-left grid item. (Hovering over it will display a tooltip. It should be the <control-0000> character. This unicode character has no width and basically means null.)
3. Click Add
4. In the Text After field, write your prefix text.
5. Choose a character style, if desired.
