Ctrl + C will copy, Ctrl + V will paste and, as part of my buy two, get one free offer Ctrl + X will cut...
I used to find that by saying Copy(c) and View (v)that it used to help me remember which buttons to press.
Also Shift + Insert should work. (I use Shift+Insert to copy and Shift+Insert to paste, but it's the same as Ctrl+C and Ctrl+V)
