Assuming that you want to extract the information from documentation:

In v37x, this information is in the plt/doc/*/keywords files.

In v3.99.x, this information isn't yet easily accessible, but it will
be available via the `scribble/xref' library. I can add that
information this afternoon.

The general answer is to use DrScheme's tool plug-in interface. In this
case, it may make sense to implement it alongside word completion,
