St uses a very good hack where mouse wheel genereates ^Y and ^E, that are the same keys that less and vi uses for backward and fordward scrolling. Scroll, as many terminal emulators, use shift+Prev/Next for scrolling, but it is also using ^E and ^Y for scroling, characters that are reserved in the POSIX shell in emacs mode for end of line and yanking, making scroll unsable in st. This patch adds a new hack, making shift+wheel returning the same sequences than shift+Prev/Next, meaning that scroll or any other similar program will not be able to differentiate between them.master
