What is the workflow between iWork apps with iCloud?

Question

I have Numbers and Pages for iOS and the Mac. With iOS 5, I can create documents and spreadsheets in iCloud. How can I access those same iCloud documents in the Mac versions? Even better yet, if I want to create a document in the Mac version, how can I save it in iCloud to begin with?

I have upgraded to the latest OS X Lion version (10.7.2) and while I see the new iCloud preference pane un System Preferences and I have enabled Documents In The Cloud, I cannot see to find their counterparts in the Mac iWork apps. Can someone point me in the right direction? Thanks.
