Is there a reason this would be greyed out, both the toolbar icons and under layer -> distribute?
As I understand it, you actually need layers selected for this to work -- but that doesn't change anything. I've tried selecting multiple layers, I've tried selecting multiple layers with an area selected in the document. Nothing. The align tools work but distribute tools remain greyed out. Is there something I'm missing?
You need to have at least 3 layers selected for the Distribute options with the Move Tool or Layer>Distribute to work.
Boy do I feel dumb. This is definitely it. When I previously tried three layers, one was locked, otherwise I was only selecting two. Thanks!
