|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).
