How do I convert a text frame back to a regular object?

Occasionally I'll accidentally click the type tool on an object or a photo and turn it in to a text frame without realizing it, and by the time I catch it it's too late to back up and undo. Is there any way to convert the text frame back into a regular object at this point? Otherwise I have to re-create the whole shape, since copying/pasting it just retains the text frame attribute.

Thanks for any advice!
