Select Multiple Swatches

[Jeremy Bohn 56]

I accidentally created a bunch of swatches in my document. I don't know how. Anyway, the only way I can see to remove them is to click them one at a time and right-click, Delete, then confirm. This is quite tedious.

Is there a way to select multiple swatches at once? In InDesign you could shift click then just press the delete key in one step.
