Window Snap Grid

An AutoHotkey v2 script that snaps windows to a 9-point grid across multiple monitors, with intelligent handling of various taskbar configurations.

Hotkeys

Hotkey	Action
Ctrl+Shift+Win+S	Center
Ctrl+Shift+Win+W	Top center
Ctrl+Shift+Win+X	Bottom center
Ctrl+Shift+Win+A	Left center
Ctrl+Shift+Win+D	Right center
Ctrl+Shift+Win+Q	Top-left
Ctrl+Shift+Win+E	Top-right
Ctrl+Shift+Win+Z	Bottom-left
Ctrl+Shift+Win+C	Bottom-right

Taskbar Compatibility

• Standard Windows taskbar — full multi-monitor support
• SmartTaskbar — detects when taskbar is hidden and adjusts work area accordingly
• Windhawk — taskbar-auto-hide-when-maximized — reads the primaryMonitorOnly setting; secondary monitors using native auto-hide have their full screen height restored
• Windhawk — taskbar-on-top — reads per-monitor taskbarLocation and taskbarLocationSecondary registry settings and adjusts top/bottom boundaries per monitor accordingly

Configuration

Edit config.ini (copy from config.example.ini if it doesn't exist):

[Settings]
# Pixels between window bottom and taskbar (0 = flush against taskbar)
TASKBAR_GAP=0

# Optional extra inset from all screen edges in pixels (0 = flush; per-app DWM frame bleed is handled automatically)
SCREEN_EDGE_MARGIN=0

Requirements

• AutoHotkey v2
• Windows 10/11
