2. Open up this script in "Raw" (or go to this url: [https://gist.github.com/amunchet/4cfaf0274f3d238946f9f8f94fa9ee02/raw/0b84970f89e1f282f09b86d46227eda71178c040/noVNCCopyPasteProxmox.user.js)](https://gist.github.com/ergoz/8a1dd8d45796f45cf3a24d888198e90f/raw/6ee61a613235372b9cd0afcd9e0e765167706e59/noVNCCopyPasteProxmox.user.js)
3. Click install
4. [Optional] if you have a non-US keyboard layout, you may need to modify the script.
5. Copy some text to your clipboard (highlight some text and Ctrl + C)
6. Open up your Promox console
7. Right click to paste the text into the console (you may need to restart your browser, depending on your tampermonkey installation)

Note: if you use LXC containers, you do not need this script, as you can just copy and paste normally from that terminal.
