BASIC KEYBOARD SHORTCUTS.
No matter what program you’re running, Ctrl+Z will roll back your last action. Whether you’ve just overwritten an entire paragraph in Microsoft Word or deleted a file you didn’t mean to, this one is an absolute lifesaver.
Another shortcut that works just about everywhere, Ctrl+W will close down whatever you’re viewing. Shut that File Explorer window, browser tab, or open image file without bothering to hone in on the close button.
This command lets you highlight all the text in a document or select all the files in a folder. Hitting Ctrl+A can save you time you’d otherwise spend clicking and dragging your mouse.
Alt+Tab: Switch apps
This baby is one of the classic Windows shortcuts, and it can be hugely useful when you’re running multiple applications. Just press Alt+Tab and you’ll be able to quickly flick through all your open windows.
Alt+F4: Close apps
Another old-school shortcut, Alt+F4 shuts down active apps so you can skip the process of hunting down their on-screen menus. Don’t worry about losing unsaved work with this command—it will prompt you to save your documents before closing
Win+D: Show or hide the desktop
This keyboard combo minimizes all your open windows, bringing your home screen into view. If you store rows and rows of files and shortcuts on your desktop, Win+D will let you access them in in moments.
Win+left arrow or Win+right arrow: Snap windows
Snapping a window simply opens it on one side of the screen (left or right, depending on which arrow you hit). This allows you to compare two windows side-by-side and keeps your workspace organized.
Win+Tab: Open the Task view
Like Alt+Tab, this shortcut lets you switch apps, but it does so by opening an updated Windows application switcher. The latest version shows thumbnails of all your open programs on the screen.
Tab and Shift+Tab: Move backward and forward through options
When you open a dialog box, these commands move you forward (Tab) or backward (Shift+Tab) through the available options, saving you a click. If you’re dealing with a dialog box that has multiple tabs, hit Ctrl+Tab or Ctrl+Shift+Tab to navigate through them.
Ctrl+Esc: Open the Start menu
If you’re using a keyboard that doesn’t have a Windows key, this shortcut will open the Start menu. Otherwise, a quick tap of the Windows key will do the same thing. From there, you can stay on the keyboard and navigate the Start menu with the cursor keys, Tab, and Shift+Tab.
