Script Docker VM Shortcuts copy + paste

Hello everyone,

Can someone explain to me why the shortcuts in the image don't work?

regards Martin

Copy/paste in Proxmox VMs often does not work because the VM console in PVE is not a native RDP/VNC client with full clipboard integration. It is basically a browser-embedded noVNC console, and browsers do not have direct clipboard passthrough to a remote framebuffer session unless they implement additional clipboard APIs. Proxmox only supports limited text copy events (e.g. CTRL+SHIFT+V), and even that works inconsistently depending on browser security restrictions.

Tools like TamperMonkey work because you can inject JavaScript into the noVNC page and handle clipboard events manually. The script can read/write clipboard via the browser Clipboard API and push that text into the noVNC text buffer. So with TamperMonkey you create your own clipboard bridge that Proxmox does not natively provide.
