If the window you're closing contains an open document, you may be prompted to save or dismiss that document before the window will close. If you aren't able to use the mouse or prefer a keyboard shortcut, you can also press ⌘ Cmd+Q on the keyboard to close the active window. This keyboard shortcut works in the same way as clicking the red circle at the top-left corner.  If you're using an app with tabs, such as a web browser, this shortcut will close the active tab only. To close all open tabs in the window, keep pressing ⌘ Cmd+W until all are closed. To close all open windows at once, press ⌘ Cmd+⌥ Option+W. Minimizing a window doesn't completely close it, but it does remove it from the screen until you need to bring it back into view. You can re-open the minimized window by clicking its icon at on the far-right side of the Dock. To minimize all open windows at once, press ⌘ Cmd+⌥ Option+M. Pressing this key will return you to your Mac's desktop immediately. When you're ready to re-open the windows you've hidden, just press Fn+F11. This command makes it look like the window is no longer open even though you're not closing the app. When you're ready to go back to the hidden window, click its application icon to re-open it. To hide all windows at once, press ⌘ Cmd+⌥ Option+H.
