This isn't the cloud offering, but on-prem. I assume they're the same.

The about page says "Confluence 6.15.2".

When I click "Edit" to edit a page, via `/pages/editpage.action?pageId=`, and hit Ctrl-S, it takes me back to the view mode rendered via `/display/SPACE/Page+Title`.

Absolutely infuriating and wastes an incredible amount of time. I can't get over my muscle memory. The "Save" button in the bottom-right does the same and appears to be what the hotkey activates. No mention of it being a "Save and Quit Editing". Hovering over the button says "Save your page (Ctrl-S)".
