C # Detect Key Press, don't use enter keys

Question

Is there a way to jump to the method if the key pressed does not result in dialing. those. shift key, control key, etc., without specifying all of them. Ideally for detecting keyboard shortcuts like Control + V = Paste.

Code similar to the one below is what I work with;

    if( (e.KeyData == Keys.Left) 
        || (e.KeyData == Keys.Right) 
        || (e.KeyData == Keys.Home) 
        || (e.KeyData == Keys.End) 
        || (e.KeyData == Keys.Up) 
        || (e.KeyData == Keys.Down)
        || (e.KeyData == Keys.ShiftKey)
        || (e.KeyData == Keys.ControlKey)
        ) return;

But you do not need to add each key combination.

Any ideas?

}
