Count of documents by keyword?

Is there a a good way to see the number of documents tagged with each keyword? I know I can do this one at a time but looking for a way to see the count for all keywords at once.

There’s a good way to get a count of documents with any keyword: Search for “*” instead of for a particular keyword. But to get a tabulation of “Key_1, 30 documents; Key_2, 4 documents; Key_3, 0 documents…” No, I don’t know a way to do that easily. Maybe someone else does…

Hope this helps!
