What is this dashed line called that aligns function blocks in my IDE?

Question

The SPE IDE that I use for my Python code uses this "visual cue" that looks like a vertical dashed line for alignment of (what I would call) function blocks. How can I get this option in Visual Studio 2008?

Here is what it looks like:

Answer 1

I've seen it called structural highlighting or code outlining.

There's a Visual Studio plug-in called CodeRush from Developer Express that supports this (bottom of the page) and a lot more.

update:

As divo mentioned, there is a free lite version of CodeRush. I confirmed that it includes structural highlighting.

Answer 2

Unfortunately, Visual Studio does not support indentation lines out of the box.
