Copy & Paste within SSH session

Hello.

I made a setting yesterday that worked like a champ, but when I closed down RDM, I guess it did not save.

I have a few SSH shell entry sessions with SFTP set to automatically open the file transfer window (I move stuff back and forth quite a bit), with default folders both local and remote.

Every new SSH shell entry I create, when I copy something from my local machine and do a Ctrl-V in the SSH shell terminal window, I get the "^V", and I have to right-click and Paste in the SSH terminal window.

Yesterday, I obviously changed something, somewhere, that allowed me to do a simple Ctrl-V of my keyboard in the SSH shell terminal window, and it pasted my clipboard contents.

What change did I do for that, and where do I find it again!?
