Four things, one app.

And the details you notice in week two.

• Chain three or more

  Laptop, desktop, test box: crossings hand off machine to machine like one long desk, and the clipboard works between any pair of them.

• Switch from the keyboard

  Ctrl+Alt+2

  Jump straight to a machine instead of dragging the cursor across three screens — the number is its position in your layout. Double-tap Ctrl to snap control back to the computer you're sitting at, even if the network stalls.

• Lock input where it is

  Ctrl+Alt+L

  Pin the keyboard and mouse to the machine you're on so a stray cursor can't wander mid-sentence. Same chord to release it.

• Flip a screen into a display

  Ctrl+Alt+M

  Turn the machine you're pointing at into an extra monitor, and turn it back into a computer when you're done. Part of Pro.

• It comes back by itself

  Sleep, a dropped Wi-Fi connection, a reboot — the machines find each other again and carry on, including a display you were extending onto.

• Phone and browser bridge

  Scan a QR code and send text or files from any phone or browser on your network. Nothing to install on the phone. Part of Pro.
