One keyboard for several computers: the transitions count

Two computers on one desk do not necessarily mean two keyboards needed at the same time. Software can pass input between devices. The idea is practical: the pointer moves across the edge of a screen, and after that keyboard input goes to the other system.
What matters is that it always stays clear which device is receiving the input. Otherwise a convenient transition quickly turns into a search for the text that disappeared.
An invented typing exercise
For a first comparison, harmless text windows on two test devices of your own would be enough. After switching, you type a short identifier and check in which window it appears. The way back is checked in the same way.
Then come the typical transitions: one device is locked, a connection drops or the screen arrangement changes. The behaviour should be understandable before the setup is used for longer tasks.
Input Leap is a public project find for this software idea. When I checked again on 11 October 2026, the repository was marked as archived since 26 July 2026. This note is therefore not a recommendation for an actively maintained project.
Keeping input and other functions apart
A shared keyboard does not automatically mean that screens are transmitted or that all files become available on both. Additional functions have to be looked at one by one in the documentation.
For your own setup, the operating systems, connection conditions and behaviour during interruptions count. The concept can already be judged with a small typing exercise. Smooth pointer movement is pleasant; an understandable and reliable input focus matters even more.
