[Wishlist] Display the QAP popup menu on double-right-click

From Marc W


2018-07-31 (JL): I did some work on it. It is possible to set mouse double-right-clicking as a trigger modifier. But this technique works and is easy to code in a standalone script when the hotkeys are saved inside the script itself. But it would be harder in QAP because it needs to save/retrieve the hotkeys selected by the user in the ini file.
