Let's kick offwith keyboard shortcuts - the first thing every power user must memorize withworking with a new operating system. In Windows 7, we've uncovered several newsets of essential time-saving shortcuts that will make your mouse jealous withneglect.
Alt + P
In Windows Explorer, activate an additional file preview pane tothe right side of the window with this new shortcut. This panel is great forpreviewing images in your photos directory.
Windows + + (plus key)
Windows + - (minus key)
Pressing the Windows and plus or minus keysactivates the Magnifier, which lets you zoom in on the entire desktop or open arectangular magnifying lens to zoom in and out of parts of your screen. You cancustomize the Magnifier options to follow your mouse pointer or keyboardcursor. Keep in mind that so far, the Magnifier only works when Aero desktop isenabled.
Windows + Up
Windows + Down
If a window is not maximized, pressingWindows + Up will fill it to your screen. Windows + Down will minimize thatactive window. Unfortunately, pressing Windows + Up again while a window isminimized won't return it to its former state.
Windows + Shift + Up
Similar to the shortcut above, hitting thesethree keys while a window is active will stretch it vertically to the maximumdesktop height. The width of the window will however stay the same. PressingWindows + Down will restore it to its previous .
Windows + Left
Windows + Right
One of the new features of Windows 7 is the abilityto automatically make a window fill up half of your screen by dragging to theleft or right. This pair of shortcuts performs the same function without yourmouse. Once a window is fixed to one side of the screen, you can repeat theshortcut to flip it to the other side. This is useful if you're extending adesktop across multiple monitors, which prevents you from executing this trickwith a mouse.
Windows + Home
This shortcut performs a similar function tohovering over a window's peek menu thumbnail in the Taskbar. The active windowwill stay on your desktop while every other open application is minimized.Pressing this shortcut again will restore all the other windows.
Windows + E
Automatically opens up a new Explorer window toshow your Libraries folder.
Windows + P
Manage your multiple-monitor more efficientlywith this handy shortcut. Windows + P opens up a small overlay that lets youconfigure a second display or projector. You can switch from a single monitorto dual-display in either mirror or extend desktop mode.
Windows + Shift + Left
Windows + Shift + Right
If you are using two or more displays (and whoisn't, these days?), memorize this shortcut to easily move a window from onescreen to the other. The window retains its and relative position on thenew screen, which his useful when working with multiple documents. Utilize thatreal estate!Windows + [Number]
Programs (and new instances) pinned to yourTaskbar can be launched by hitting Windows and the number corresponding to itsplacement on the Taskbar. Windows + 1, for example, launches the firstapplication, while Windows + 4 will launch the fourth. We realize that this isactually one key-press more than just clicking the icon with your mouse, but itsaves your hand the trouble of leaving the comfort of the keyboard.
Windows + T
Like Alt + Tab (still our all time favoriteWindows specific shortcut), Windows + T cycles through your open programs viathe Taskbar's peek menu.
Windows + Space
This combo performs the same function as movingyour mouse to the bottom right of the Taskbar. It makes every active windowtransparent so you can view your desktop. The windows only remain transparentas long as you're holding down the Windows key.
Ctrl + Shift + Click
Hold down Ctrl and Shift while launching anapplication from the Taskbar or start menu to launch it with fulladministrative rights.
Ctrl + Click
Hold down Ctrl while repeatedly clicking aprogram icon in the Taskbar will toggle between the instances of thatapplication, like multiple Firefox windows (though not browser tabs).
