Copy & Paste

LLrdc supports bidirectional clipboard synchronization between your host browser and the remote desktop environment. This allows you to seamlessly transfer text back and forth.

Copy & Paste from Host to Remote

There are two primary ways to send text from your local machine to the remote desktop:

1. Keyboard Shortcut (Cmd+V / Ctrl+V)

This method works immediately. When you paste using your keyboard shortcut, the browser captures the text, sends it to the remote server, and injects Ctrl+V into the active remote application.

2. Context Menu Paste

After you have pasted at least once via the keyboard shortcut (which syncs the remote clipboard state), you can use the right-click menu and select Paste directly within remote applications.

Copy from Remote to Host

Text copied within the remote desktop (for example, by highlighting text in a terminal and pressing Ctrl+C or using the context menu) is automatically synchronized to your host browser’s clipboard.

Note: The synchronization from the remote desktop to your local clipboard takes approximately 1 second.

Disabling the Clipboard

While convenient, bidirectional synchronization requires continuous focus polling of the HTML viewer to access the host’s clipboard. If this causes performance issues or interferes with your workflow, you can disable it either at runtime or at startup:

At Runtime

Open the LLrdc web viewer configuration panel, navigate to the Input tab, and uncheck Enable Clipboard Sync.

At Startup

You can permanently disable it by starting the server with the flag --enable-clipboard=false or by setting the environment variable ENABLE_CLIPBOARD=false.
