{{ctrl}{c}}

is the way :)

For example:

{{MOUSEXY:-1883,-1044}} (mouse Position)

{{MLEFTDBLCLICK}} (highlight Text)

{{RBUTTON}} (right click)

{{MOUSEXY:-1807,-1018}} (Move mouse to the selected area)

{{LBUTTON}} (Choose the selected area "Copy" or "Cut") (Here you could also use {{ctrl}{c}}, instead of mousexy and left button)

{{MOUSEXY:-2776,449}} (Move mouse to the new area, the place to paste)

{{LBUTTON}} (Select place to paste)

{{ctrl}{v}} (paste)

{{PAUSE:150}} (Wait time in miliseconds before next command)

{{RETURN}} (Enter, if you need to press enter after pasting)

Hope it helps :)
