Hot corners

Start useful actions from any screen corner.

Move into a screen corner to start a screensaver, lock, open the custom menu, show the desktop, launch an app, or perform another useful action.

Corners can belong to the primary display, every display, or the combined desktop. Dwell time, activation radius, and rearming prevent accidental triggers.

Turn display corners into fast, deliberate actions.

Hot corners across multiple monitors

Stacked, offset, and joined monitors are handled as a real desktop rather than one imaginary rectangle.

Control corner size and activation delay

Set the radius and dwell, ignore dragging, and require the pointer to leave before a corner can fire again.

Start screensavers, open your menu, or lock your screen

Start one screensaver, open your menu, lock, toggle the desktop, or jump directly to Settings.
