+Subject: [PATCH] universcroll: mouse wheel only scroll in all modes
+
+Scroll normally via scroll(1), without Shift, when outside of
+`MODE_ALTSCREEN`. Inside an alt screen, continue to scroll normally
+without Shift; in this mode, your scrolling is automatically translated
+into ^Y and ^E. It just werks!
+
+Based on the existing mouse-altscreen patch
+https://st.suckless.org/patches/scrollback/
+adapted for st(1) 0.8.4 and scroll(1).
