If you use Chrome, you are asked if you would like to allow cutting and pasting, and then cut and paste will just work.
However, if you are using a different browser, the normal cut and paste shortcuts will not work in the DCV web client. These are directions for you.
To paste from your local machine to the DCV desktop - Select the local text and copy it. - Choose “Paste to Remote Session” from the icon menu in the upper left of the window (see below).
To paste from the DCV web client back to your local machine - Select the text and copy it. - Choose “Copy to Local Device” from the icon menu in the upper left of the window. - A window will open fleetingly, and close. - Go to your local desktop and use normal paste commands.
If your connection times out, you can reconnect by generating another link.
pcluster dcv connect -k ~/.ssh/neuropoint-key npointclust
Select this entire link and paste it into a browser tab.
