[accepted] Clipboard Manager double-click-to-clear?

For two-button mice, is the middle-click Ctrl+Left-click or Ctrl+Right-click or something else? Does a wheel-click register as a middle-click?

Wheel-click is the same as middle-click. It is possible to make the option and handle both middle-click and double-click.

If you make it a click rather than a shortcut possibility, I can't put it in a bat file and run it with an event-sound. Or can I?

Is the problem in the sound only? I can add more sounds options.
