How do I fix my auto indent in Textmate?

I'm editing a django templ开发者_如何学JAVAate.

When I press enter while my cursor is between html tags:

<div|</div>

Textmate indents with three spaces:

<div>
   |
</div>

This is driving me crazy. (I want four spaces!)

When my cursor is between tags, Textmate tells me that my current scope is

• text.html.django
• meta.tag.any.html
• punctuation.definition.tag.html
• meta.scope.between-tag-pair.html

Where do I find the setting that controls the number of spaces Textmate indents with?

There's a little menu that might display Tab size: 3 at the bottom of the window. Whatever you set here is supposed to stick.
