One click from the Actions menu
Choose “Show only the window in front”. The picture is cut to that window's area on the remote computer before it is encoded, so only those pixels travel (anything placed over the window shows too).
Follows the window
Move or resize the window and the view follows while it has focus — even onto another monitor. Mouse, keyboard and drawing stay lined up. Available on Windows, macOS and Linux (X11).
Back to the full screen any time
“Show the whole screen again” restores the normal view instantly.
Frequently asked questions
Does sharing one window use less data?
Yes. Only the window's area is captured and encoded, so the stream is smaller than the whole desktop.
