I want to know if Ctrl is pressed with "C" twice fast so my program speaks the text in clipboard.

What I have tried:

static globalKeyboardHook gkh = new globalKeyboardHook();

static void gkh_KeyUp(object sender, KeyEventArgs e)
        {
            switch (e.KeyCode)
            {


                case Keys.LControlKey:
                    LCTRLPRESSED = false; break;
             }
        }

static void gkh_KeyDown(object sender, KeyEventArgs e)
        {
            switch (e.KeyCode)
            {


                case Keys.LControlKey:
                    LCTRLPRESSED = true; break;
             }
        }

But this sometimes causes my program to speak the text without Ctrl being pressed when "C" is pressed twice fast, as Ctrl lags as being down till I press it again and it updates to being up.

There's:
if(e.Control) {;}

But it doesn't work correctly.

There's also e.Modifiers, does it work? if yes how?
