Guides / Edge snapping

Edge snapping

Drag a window to a screen edge and release: it fills a half, a quarter, or the whole screen. It is off by default.

Turn it on

  1. Open Settings… from the tray menu.
  2. Under Snapping, switch Edge snapping on.
  3. Set Edge size: how close to the edge the cursor must be, from 2 to 64 px. The default is 8 px.

What each edge does

Edge snapping map. Left and right edges give halves, the top edge maximizes, the four corners give quarters, and the bottom edge between the corners does nothing. Quarter Quarter Quarter Quarter Maximize Left half Right half Nothing cursor here: no edge snap
The bands are as wide as your Edge size setting; they are exaggerated here.
Cursor atThe window fills
Left edgeThe left half of the monitor
Right edgeThe right half
Top edgeThe whole work area (maximize)
A cornerThat quarter of the monitor
Bottom edge, between the cornersNothing: that is where the taskbar or Dock lives

How it behaves

  • No key needed. Drag, move the cursor to an edge, and a preview of the target appears; release to snap. Move away from the edge and the preview goes.
  • Zones win. While you hold the activation key and the zones are showing, edge snapping is off, so the two never fight.
  • Never between monitors. A side only counts if no other monitor touches it at that point. See Multiple displays.
  • Work area. Halves and quarters are cut from the monitor’s work area, which excludes the taskbar, menu bar and Dock.
  • No gap. The Space between zones setting applies to zone snaps, not to edge snaps, which fill their half or quarter exactly.
  • Windows’ own edge snapping stays on. Krova does not switch it off. If both react to the same edge, turn one of them off; they have not been tested together.
