A variety of new keyboard shortcuts have been introduced in windows 7.

Global keyboard shortcuts:

    * Windows key + Space bar operates as a keyboard shortcut for Aero Peek.
    * Windows key + D to show the desktop
    * Windows key + Up maximizes the current window.
    * Windows key + Down if current window is maximized, restores it; otherwise minimizes current window.
    * Windows key + Shift + Up maximizes the current window, in the vertical direction only.
    * Windows key + Left snaps the current window to the left edge of the screen.
    * Windows key + Right snaps the current window to the right half of the screen.
    * Windows key + Shift + Left and Windows key + Shift + Right move the current window to the left or right display.
    * Windows key + + (plus sign) functions as zoom in command wherever applicable.
    * Windows key + - (minus sign) functions as zoom out command wherever applicable.
    * Windows key + ESC (Escape key) turn off zoom once enabled.
    * Windows key + Home operates as a keyboard shortcut for Aero Shake.
    * Windows key + P shows an "external display options" selector that gives the user the choice of showing the desktop on only the computer's screen, only the external display, with the same output on both (clone), or on both displays with independent desktops (extend).

Taskbar:

    * Shift + Click, or Middle click starts a new instance of the application, regardless of whether it's already running.
    * Ctrl + Shift + Click starts a new instance with Administrator privileges; by default, a User Account Control prompt will be displayed.
    * Shift + Right-click shows the classic Window menu (Restore / Minimize / Move / etc.); right-clicking on the application's thumbnail image will also show this menu. If the icon being clicked on is a grouped icon, the classic menu with Restore All / Minimize All / Close All menu is shown.
    * Ctrl + Click on a grouped icon cycles between the windows (or tabs) in the group

Enjoy!!!
