what is the printscreen key on a laptop
Print screen In Microsoft Windows, pressing Prt Sc will capture the entire screen,[1] while pressing the Alt key in combination with Prt Sc will capture the currently selected window.[1] The captured image can then be pasted into an editing program such as a graphics program or even a word processor. Pressing Prt Sc with both the left Alt key and left ⇧ Shift pressed turns on a high contrast mode (this keyboard shortcut can be turned off by the user).[2] Since Windows 8, pressing the ⊞ Win key in combination with Prt Sc(and optionally in addition to the Alt key) will save the captured image to disk (the default pictures location).[3] This behavior is therefore backward compatible with users who learned Print Screen actions under operating systems such as MS-DOS.
