How to reference an indexer member of a class in C# comments

Question

In order to reference a member of a class in XML comments/documentation, you have to use the following tag:

<see cref="member"/>

It is better explained here.

How do you reference an indexer?

I mean, a member like this one:

internal object this[ int index ] {
    ...
}

Thanks in advance.
