It doesn't have to be employed everywhere, and employing it everywhere doesn't make it slow. It would work for POS systems. And if it was put into a generic class, it could be turned off or on with settings at design time, or run-time.

With touch-screen devices you lose the right-click. In certain places, having a long-press mimic the right-click would be desirable. This method I have outlined makes it possible. It doesn't have to be used anywhere.
