Browser Window Manager

Most window tools give you four snap zones. Left half. Right half. Need a 70/30 split? Good luck.

Window Manager ships 40+ positions across nine categories, plus unlimited custom layouts. Every position assignable to any shortcut key.

40 Window Positions. Zero Mouse Movements.

Browser Window Management

Doesn’t Exist. Until Now.

macOS has window snapping. Windows 11 has snap layouts. Linux has tiling window managers. These aren’t nice-to-haves. They’re infrastructure.

Your browser has none of this. The application where you spend the majority of your working day gives you basic snap zones at best.

You need two pages side by side. You get left half and right half. Maybe quarters. That covers 20% of real layouts.

What about a three-column documentation setup? A 70/30 split for your ultrawide? A presentation-sized window centered on screen with exact margins?

Most snap tools give you positions. SEO Time Machines gives you a system: 40+ presets, unlimited custom positions, and the ability to assign any of them to any shortcut key—then launch from the keyboard or the command palette.

Quick Launch Integration

Type w. Every Position Appears.

Press Ctrl+Shift+Space. The Quick Launch Toolbar appears. Type w.

Every window position appears—categorized, with preview thumbnails, showing which shortcut key each one is mapped to. Click any position to execute it. Or type to filter.

You Type	What Happens
w (space)	All 40+ positions appear, organized by category
w0 through w9	Executes the position assigned to that slot instantly
w center	Filters to Center Half, Center Two-Thirds, Center Three-Fourths
w third	Filters to First Third, Center Third, Last Third, First Two-Thirds, Last Two-Thirds
w half	Filters to Left Half, Right Half, Top Half, Bottom Half

One letter to open. One more to filter. Click or press Enter to execute.

That system pairs with eleven other productivity tools for keyboard-driven workflows.

The Numpad Grid

Spatial Memory Beats Recall

Your numpad is a map of your screen. The key layout mirrors the screen layout.

Key	Position
7	Top-Left Quarter
8	Top Half
9	Top-Right Quarter
4	Left Half
5	Almost Maximize
6	Right Half
1	Bottom-Left Quarter
2	Bottom Half
3	Bottom-Right Quarter
0	Maximize

Press Ctrl+Alt+Cmd+7. Window snaps to top-left quarter. Press 3. Bottom-right quarter. Press 0. Maximize. No menus. No searching. Your fingers already know where the positions are.

After a week, you stop thinking about it. After a month, window positioning is reflex—as automatic as Cmd+C for copy.

Every slot is reassignable. Swap slot 5 from “Almost Maximize” to “Center Two-Thirds” if that’s your primary working layout.
