How to Snap a Window Across Multiple FancyZones

You’ve divided your screen into perfectly shaped little corners with FancyZones — but not every app or window fits neatly inside them. Instead of reshuffling your layout, let certain windows occupy more than one area. Find out here how to snap a window across multiple zones with MS PowerToys FancyZones ⤓.

First, Letter to River and Air

Back when a crop-dusting company decided to carry people to the air and clouds in 1928, its name — Huff Daland — no longer fit. The CEO wanted something short, something that could lift.

Catherine Fitzgerald, the assistant, thought of the river and its delta that had fed their crops. “Delta,” she suggested. The name took flight.

Delta Air Lines kept the name and its triangular mark, echoing the Greek letter Δ and its reflection in river deltas like the Mississippi’s.

Now, how about letting a window gracefully stretch the same way across FancyZones — without ever leaving the ground?

Snap a Window to Multiple Zones Using Just the Mouse

To use only the mouse to snap a Window to more than one FancyZones zone:

1. Set up the right mouse button to trigger FancyZones snapping; see below.
2. Start dragging the window with the left mouse button and, while still dragging with the left, click the right mouse button in addition.
3. Drag the window to the border between two zones or the corner between zones.
   Like “Ctrl”. With middle mouse button enabled, press the middle mouse button in addition to the other two to have selecting zones behave as if you would hold the Ctrl key.
4. Release the left, then the right mouse button as all desired zones have lit up.

To allow snapping windows to multiple zones using the keyboard in FancyZones:

1. Open FancyZones settings in PowerToys.
2. Turn on Override Windows Snap.
3. Set Move windows based on to Relative position.
   Here’s why: With this setting, the window is sure to move to an adjacent zone and can occupy both; with Zone index set, snapping a window to multiple zones with keyboard shortcuts does not work.
