This may feel unintuitive because generally you expect to be able to type in a window once you click on it. Now user B clicks on some other window and expects to start typing in that window – but since the keyboard is paired with user A, and user A did not click on any other window user B will keep typing in notepad! Practically speaking user B does not have a keyboard – he/she just follows what the focus window is of user A. User B takes over and types on the same keyboard. User A clicks on notepad and starts typing. Both users are interacting with the desktop with their own mouse. User A and B sit behind the same computer, there are two mice attached and one single keyboard. Working with paired keyboards may feel unintuitive at first here’s a use case to explain why.

You will see both the mouse and keyboard light up orange in the row of your user number. Pairing is simple: move a mouse and hit a key on the keyboard that you want to pair. Keyboard pairing means linking a keyboard to a mouse – together they represent a (virtual) user.
