Apply the following patch on top of the previous to allow scrolling
using `Shift+MouseWheel`.

+* [st-scrollback-mouse-0.8.diff](st-scrollback-mouse-0.8.diff)
Apply the following patch on top of the previous two to allow scrollback using
mouse wheel only when not in `MODE_ALTSCREEN`. For example the content is being
scrolled instead of the scrollback buffer in `less`. Consequently the Shift
-modifier for scrolling is not needed anymore. **Note: It might break other
-mkeys excluding scrolling functions.**
