two questions: making clipboard show near mouse and intercepting calculator button on my keyboard

I have two questions:

  • I have a trigger to show the clipboard. Is it possible to make it so clipboard shows up near my mouse? Right now it shows up in the same spot.
  • I have a calculator button on my keyboard. Can I intercept that for a shortcut? I want it to launch a browser. Karabiner shows the button as al_calculator.
