Aero Snap is a feature in Microsoft Windows that allows users to easily organize and manage open windows on their desktop. By dragging a window to the edge of the screen, it automatically resizes and snaps into place, filling half or a quarter of the display. This makes multitasking more efficient, as users can view multiple applications side by side. Additionally, Aero Snap supports keyboard shortcuts for quick window management. For example, pressing the Windows key along with the arrow keys can snap windows to different parts of the screen without using the mouse. This enhances productivity by simplifying the arrangement of workspace.
