Now that more and more document based applications do the modern "Save, Duplicate, Revert to" Versions thing instead of the traditional "Save, Save as, Revert". Having had 30 years becoming quite adept at the traditional workflow across many systems, I'm having trouble adapting.
In those applications using Versions, how do you save changes you've made to a document as a new file? For example, often I'll open a photo in Preview, crop it, resize it and then want to save it as a "cropped" version of the original file. Or I'll open a letter in Pages, change some details and decide I want to keep this version for a different recipient. Or open two videos in Quicktime Player, crop them both, concatenate one with the other and save the result as a new file.
It may be that that's simply not an option now, so I'm also interested in answers that describe a different workflow, that involves editing a file and somehow results in having the edits appear as a new file, leaving the original untouched. The same workflow for Versions and non-Versions applications would be great, or otherwise some good way of switching routines at the right time.
The related question of how to discard those changes in progress and revert to the last saved file has a useful answer, for now, here. And I assume the answer to this 10 year old question is sarcastic, awaiting something a bit more sensible.
