Restricting access to features
By default, while a connection is in progress, you can control the host computer using your keyboard and mouse, and in addition copy and paste text between applications running on the client and host computers.
For connections to VNC Server (Enterprise) and VNC Server (Personal), you can also:
• Print host computer files directly to a local printer.
• Exchange files with the host computer.
• Chat with other VNC Viewer users connected to the same host computer, or with a host computer user.
Note: VNC Server may have been configured to prevent some or all of these features. For more information, see Restricting functionality for connected users. In addition, VNC Viewer might have been configured to disable printing before the connection started.
You can restrict access to features while the connection is in progress by configuring options on the Inputs tab of the VNC Viewer - Options dialog. More on this dialog. You might want to do this if you are watching a demonstration on the host computer, for example, and want to prevent inadvertent interruption.

Note: You can enable features again at any time. To prevent this for the current connection only, disable the VNC Viewer toolbar and shortcut menu. For more information, see Changing appearance and behavior.
