If I quick open a file using the quick open menu, is there a keyboard shortcut that will take the opened file outside of preview mode so that when I open a new file it won't replace the currently open one?
(I'm looking for a keyboard shortcut as opposed to double-clicking the filename or tab in order to keep my workflow keyboard oriented)
Try the View: Keep Editor command (default shortcut Ctrl+K, Enter):
Note: this shortcut is a chord, meaning that Enter must be pressed after releasing Ctrl+K.
As of v1.19 (released in December 2017) Alt+Enter opens the file (after Ctrl+P) NOT in preview mode but in a "permanent", touched status.

If you would rather open the file directly from Quick Open (skipping the preview mode altogether), you can change this in the settings or add this to settings.json:
"workbench.editor.enablePreviewFromQuickOpen": false
If you want to disable previews for other means of opening files (like the project explorer), this will do the trick:
"workbench.editor.enablePreview": false
