๐น What Does Windows + Left Arrow Do?
When you press Windows + Left Arrow, the currently active window immediately snaps to the left side of the screen, occupying exactly half of the horizontal display space.
If another window is open, Windows may suggest other open windows for the right side (via Snap Assist), helping you create a split-screen view with just a few keystrokes.
This shortcut is a part of Windows’ Snap feature, introduced in Windows 7 and refined in Windows 10 and 11, to support easier multitasking on a single monitor or across multiple displays.
