article: It's best to have CO detectors located within 10 feet (3.0m) of your bedrooms. If your bedrooms are spread out across one floor, you may need more than one detector for that floor. If you can, purchase a set of detectors which can be interconnected, so when one sounds, all of them will sound. Carbon monoxide doesn't rise like smoke does. Instead, it equalizes throughout the room. This means that you can place the detector at any height and it will still give an accurate reading. If you have a digital display, placing it at eye level will make it easier to read. Although CO by itself is not lighter than air, one should note that many sources of CO also generate heat. The heated air rises in cooler air, naturally carrying the CO with it, as the CO mixes with the air. To make sure you can remember how long it's been, write the purchase date on the back or side of the unit with a permanent marker.

article: Nearly all Windows apps have an X at the top-right corner. Apps like these can typically be closed easily by clicking the X. If the window contains an open document, you may be prompted to save or dismiss it before the window will close. If the window has expanded to full-screen size and you don't see the X, press F11 to bring it back to normal size first. This keyboard shortcut will close the currently-active window just like clicking the X. If the window you're using doesn't have the X at the top-right corner, this combination of keys should do the trick. This command can be used in an app that supports multiple active documents at once, such as Microsoft Word. The app itself will not close, but the open file will. If you're using a browser like Chrome or Edge, this keyboard shortcut will close the active browsing tab without closing the browser application. Pressing the Windows Key and the down-arrow key at the same time will not close the window, but it will remove it from your view so you can work on other things. To restore a minimized window, click it on the taskbar, which is usually at the bottom of the screen. To minimize all open windows at once, press Win+M.
