Linux + Logitech how to remap keys?

Question

linux

I use a logitech m510 + ubuntu 14.04 mouse, there are 2 additional back and forth buttons on the mouse and they work out of the box the first time they are turned on. I wanted to remap the functions of the keys, the task was completed using xbindkeys and xautomation all according to this goo.gl/I4uhu3 instruction. So I can’t understand why such crutches, because somewhere in the system it is indicated that the back button is back, how to change the function of the button without crutches?

Answer 1

xbindkeys and change assignments, this is xorg's utility, not a left crutch. But why xautomation is there is unclear. Here is my ~/.xbindkeysrc:
# Mouse buttons
"xvkbd -xsendevent -text "\[XF86Back]""
m:0x0 + b:9
# Keyboard buttons
"/home/evv/.scripts/show_battery.sh"
m:0x0 + c:244
XF86Battery
