Press Scroll Lock on the keyboard in front of you. The mouse and keyboard come back to that computer at once.
No Scroll Lock key? Ctrl+Alt+Shift+Backspace does the same.
Why there are two
Many laptops have no Scroll Lock. Backspace and those three modifier keys are on every PC keyboard, with the same meaning in any layout, and Windows keeps that combination for nothing of its own.
What they do
- Your pointer is on another computer: it comes back.
- Another computer is using this one: this computer is taken back, and on the local network the other one is kept away for 30 seconds. Press again and the 30 seconds start over.
- Someone is looking at this screen: it stops.
- Control over the internet is on: it ends, and coming back takes a new approval.
Only a real keyboard
The keys work inside BukDesk's own keyboard hook, with no help from the network. Input that a program sends is not counted. So a program cannot press them, and neither can a person at another computer.
They always work
After the trial ends, with no license, with the network down: the keys still bring your mouse and keyboard home.
What they do not do
They buy time. A computer that is kept away for 30 seconds is still paired and still in your arrangement, and what it did while it had control stays done. To end it for good, take that computer out of the arrangement, or end the pairing.
A very cheap keyboard may not report four keys at once. Try both ways on your own keyboards before you rely on them.
