Cursor Crane
Overview

Mouse Control Mode

Enter it by command, by a dedicated shortcut, or by holding Space in Command Mode. If you would rather send Space normally, turn the hold-Space behavior off in Settings.

The keys may change during beta.

Movement keys#

Movement keys depend on the layout you picked during setup. In the IJKL layout, I, J, K, and L are up, left, down, and right.

By default a rectangle is drawn around the cursor, and a movement key sends the cursor to the edge of that rectangle. Because the rectangle is visible, you can see where the next press will land before you make it.

Precise movement#

Hold Shift for accuracy. The rectangle shrinks as you move, letting you close in on an exact position, usually over a few presses.

Two precision modes are available, switchable in Settings:

  • Bisection moves the cursor into the chosen half of the rectangle. Easier to learn, less precise.
  • Nine-Square Grid divides the rectangle into nine squares and moves to the center of the one you pick, then subdivides again. More precise, harder to master.

With bisection, the inner grids let you predict the path. If the target sits on the left of the rectangle but inside the inner rectangle, moving left and then right approaches it.

Change the reference rectangle#

Hold a modifier to re-anchor the rectangle:

Hold Rectangle becomes
Command The element under the cursor
Option The window
Control The active screen

This is how you cross long distances in one press, such as jumping to a window or screen edge, instead of stepping there.

Switch displays#

Number keys move the cursor to the center of a display. Each display's number appears in the status indicator at the top left.
