Hi,
Just a little patch I figured I might share here.
One thing that always annoyed me with in urxvt was how, when running
apps on secondary screen, one could not use the mouse wheel to scroll
within said app, e.g. man or less (something possible in VTE-based
terminals).
So here's a patch to change that. What it does is pretty simple: when
using the mouse wheel, if you’re on secondary screen then no scrolling
will occur, and instead some (3, to be exact) “fake” keystrokes will be
sent to the running application. So, a wheel up will have the same
result as pressing the Up key three times, and wheel down will do the
same as pressing 3 times the Down key.
This is added as a new (disabled by default) option: secondaryWheel (ssw)
I'm also including a patch from rlblaster, posted in the Arch Linux
forums (https://bbs.archlinux.org/viewtopic.php?id=129302), because I
like it a lot as well (and I believe it wasn't shared here).
When resetting the terminal (Ctrl+L), by default urxvt simply moves the
cursor on top of the window, and clears everything that was there.
Meaning that as a result, it can cut off some of your buffer, as those
lines are just cleared.
To fix this, rlblaster's patch will make it, before hand, add lines,
thus allowing to keep your full scrolling buffer intact.
It looks the same, except that when scrolling up everything is there,
nothing was cut.
There you go; Both patches are for rxvt-unicode-9.14
Hopefully this might be useful to some,
