Why

With this app you can use M575 macro buttons for edit sensivity.

Install process

You need xbindkeys. sudo pacman -S xbindkeys touch ~/.xbindkeysrc After these commands, you should edit xbindkeysrc file. Add:

"ergosniffer up"
  b:9

"ergosniffer down"
  b:8

Compile app then move to /usr/bin/ folder.

killall xbindkeys for reload xbindkeys it should work in background (I recommend autostart)
