Set Input.GetKey to true by scripting

Can i fake the Input.GetKey to an GUI.RepeatButton by setting the Input of the Key to true when pushing the Button? I tried the following, but it doesn't work. Is there any possibility? if( GUI.RepeatButton( new Rect( 30, 30, 50, 50 ), "right" ) ) { Input.GetKey(KeyCode.RightArrow) = true; Debug.Log(Input.GetKey(KeyCode.RightArrow); }
