Why can't I save through command-S?

When saving a document in .docx or .odt, I don’t have the option to quick-save through Command-S. It doesn’t make sense that I need to “Save As” every time I want to save my work during the editing process. What am I doing wrong?

If you want to quick-save - Ctrl+S, if you want to save as… - Ctrl+Shift+S

Hi Anonymous, are you working on a Mac?
