Keyboard Shortcuts

Keyboard shortcuts for the LabTether web console, terminal viewer, and desktop viewer. In interactive sessions (terminal and desktop), most keyboard input is forwarded directly to the remote machine -- use the toolbar or these documented shortcuts to control the viewer itself.

Console (global)

Shortcut Action
/ or Cmd+K / Ctrl+K Open search
Esc Close modal, dismiss panel, or exit search
? Show keyboard shortcut help (when not in a text field)

Terminal viewer

Shortcut Action
Standard typing Forwarded to remote shell
Ctrl+C Send interrupt to remote process
Ctrl+D Send EOF (close shell if at empty prompt)
Ctrl+Z Suspend foreground process
Paste (Cmd+V / Ctrl+V) Pastes clipboard content into the remote terminal
Ctrl+Shift+C (Linux/Windows) Copy selected text from terminal
Ctrl+Shift+V (Linux/Windows) Paste into terminal

Tip: On macOS, Cmd+C and Cmd+V work naturally for copy and paste in the terminal viewer. On Linux and Windows, use Ctrl+Shift+C/V to avoid sending Ctrl+C (interrupt) to the remote shell.

Desktop viewer

Shortcut Action
Standard typing Forwarded to remote desktop session
Mouse movement and clicks Forwarded to remote desktop session
Viewer toolbar buttons Control session features (clipboard, recording, display selection, quality)

Special key handling: Browser shortcuts like Ctrl+T (new tab), Ctrl+W (close tab), and F11 (fullscreen) are intercepted by the browser, not sent to the remote session. For keys that conflict with browser shortcuts:

  • Use the Send Key toolbar menu to send Ctrl+Alt+Del, function keys, and other special combinations to the remote machine.
  • In fullscreen mode, fewer browser shortcuts intercept, so more keys reach the remote session.

Embedded noVNC controls

When using VNC in embedded mode, the dock below the viewer provides session controls. In fullscreen mode, use the overlay toolbar:

Control Action
Mouse Hands pointer control to the remote viewer
Keyboard Sends typing to the remote session
Clipboard Push/pull clipboard content
Display Select which monitor to view (multi-monitor targets)
More Additional shortcuts and display settings

Tip: If the remote desktop session seems to ignore your keyboard input, click inside the viewer to ensure it has focus. Some browsers require an explicit click after switching tabs.
