It's possible to enable Ctrl+C / Ctrl+V in IRIS Terminal for Windows.
To do that, open Terminal and select Edit > User Settings and enable Windows edit accelerators. This setting specifies whether the Terminal enables the common Windows edit shortcuts (Ctrl+C, Ctrl+V, Ctrl+Shift+V), in addition to the basic Terminal edit shortcuts (Ctrl+Insert and Shift+Insert).
After that Ctrl+C / Ctrl+V would work.
Also <SYNTAX> errors after incorrect copy/paste go away.
