@ -164,6 +164,31 @@ acme -W spec
where spec can be WIDTHxHEIGHT, WIDTHxHEIGHT@XMIN,YMIN
'XMIN YMIN XMAX YMAX' or XMIN,YMIN,XMAX,YMAX.
* Mouse scrolling
The libraries pass along buttons 4 and 5, so if you have a
scroll mouse and have X configured to send the up/down
events as buttons 4 and 5, acme and 9term will scroll in
response.
You will likely need to change your X config to enable this.
In my XF86Config-4 I have
Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Buttons" "5"
Option "Emulate3Buttons" "off"
Option "Protocol" "ImPS/2"
Option "ZAxisMapping" "4 5"
Option "Device" "/dev/psaux"
EndSection
You'll want to find your mouse section (which may have
a different Identifier -- just leave it alone) and edit that.
The "Buttons", "Protocol", "ZAxisMapping", and "Emulate3Buttons"
lines are all important.
* Helping out
If you'd like to help out, great!
