Move the pointer past the edge of one screen. It carries on, on the next computer. What you type goes to the computer the pointer is on.

How it connects

  1. Install BukDesk on each computer.
  2. On one, press "Pair now". On the other, type its serial, or pick it from the list of computers on the network.
  3. A six-digit code shows on both screens. Check that it is the same code, and press on both.

There are no IP addresses to type. A serial is 20 characters, and it comes from the computer's own encryption key.

You pair once. After that the computers find each other and connect by themselves.

You say where each computer sits

On the "Arrange" screen you drag each computer to the side where it stands on your desk: left, right, above or below. The pointer crosses at that edge. A computer you have not placed gets no say over your mouse, keyboard or clipboard.

What it runs on

  • 64-bit Windows.
  • The same local network, which Windows has to call private. Connecting computers on different networks, over the internet, will be Premium, which arrives with launch.
  • No driver. The app runs as you, with no administrator rights.

What is encrypted

Everything between two paired computers is encrypted and authenticated, with keys that only those two computers hold. Someone on the same network can see that traffic is flowing and how much. They cannot read it or change it.

While you type, input goes out in frames of one size on a steady tick, so the rhythm of your typing does not show to someone watching the network.

Where the pointer cannot go

  • Windows running as administrator.
  • The Windows lock screen and sign-in screen.

Windows does not let a program that runs as you send input to either one, and BukDesk runs as you.

The way back

Scroll Lock brings the mouse and keyboard back to the computer you press it on, at once. See the emergency keys.

What pairing means

A paired computer that you have placed next to yours can type and move the pointer on it. That is the point, and it is a real grant. Pair only computers that are yours. The six-digit code shows that the two screens in front of you share one session. It says nothing about who is at the other end.
