Outdenting first line of a paragraph?

Anyone have a trick / shortcut for outdenting the first line of a paragraph of text?

Usage: bulleted lists where the list item wraps in the shape.

I’m looking for something more automatic / less clunky than a hard return and adding spaces / tabs, as this approach breaks whenever the shape is resized.

When you’re editing text, OmniGraffle replaces the standard horizontal ruler with a text ruler, which contains controls for setting first-line and hanging indents as well as tab stops.

Does this look like what you’re after?

Ah, yes, that’s exactly what I was looking for. Thanks!
