How do I find which features are dependent on a sketch?

In a complex model, there are sketches that I don't think I need anymore.  I would like to delete them but I first want to be sure that doing so won't bugger up other things.

Is there a way to easily find out if there are other features that depend on a sketch?  I'm thinking of some way to query for relations that refer to the sketch in question.

Thx.
