Scheduled publishing in EPiServer

Everyone knows how to schedule a publication of a new version of a page in Epi. But every now and then I get the question on how to publish a new version of an already published page. And everytime I am asked that I need to refresh my own memory (i.e Google it up) , since I almost never do this.
I found a neat step by step guide describing how to do it:

1. Edit the page with your changes. Leave publish dates as is, you will set your date elsewhere.
2. Select "Save and view" (NOT PUBLISH!)
3. Two buttons are displayed, click "Ready for publish".
4. Goto the version list tab.
5. Last in the listing where your new version is there's a time schedule icons to the right. Click on it.
6. Tick the activate checkbox and enter time and date as you please.
7. Save and your new version of the page is now awaiting automatic publishing.
