I asked this question about a week ago and received no response, so
I'm trying again with more information.

I discovered an icon displayed in Visual Studio .NET in a downloaded
example program that I have never seen before. I have no idea what it
is or what it means.

The icon is in the Margin Indicator Bar (where breakpoints are
displayed) and is not documented at MSDN.

marginwidgets.asp)

In my previous message, I simply described what the icon looked like.
Since this might be hard for people to visualize, I created a
screenshot of the icon this time. Here it is:

Does anyone know what this is?
