Simple keyboard toggle switch?

Hey everyone. I'm trying to create a simple keyboard toggle switch. When a key is pressed, the application should pause. When the same key is pressed again, the application should resume. Here's what I have so far. Many thanks for the help.

boolean pause = false;

void keyPressed() {
  if ((key == 'x' || key == 'X') && (pause = false)) pause = true; noLoop();
  if ((key == 'x' || key == 'X') && (pause = true)) pause = false; loop();
}

GoToLoop

boolean isPaused;

void draw() {
  background((color) random(#000000));
}

void keyPressed() {
  if (isPaused ^= keyCode == 'X')  noLoop();
  else                             loop();
}
