I'm following [this tutorial](https://blog.hanschen.org/2009/10/13/mouse-shortcuts-with-xbindkeys/) but cant seem to get this working

I used xev and confirmed the two mouse buttons I want to map are button 8 and button 9

I want to map them to the "a" and "s" keys on the keyboard.

I tried the following variations in my .xbindkeysrc but it doesn't do anything when I click my mouse buttons (I confirmed that remapping keyboard keys to commands like "xterm" does work).

```
"a"
  b:8

m:0x0 + c:38
  b:8

xte 'key a'
  b:8

xte 'key 0x61'
  b:8

```

Also tried these variations with "b:8 + release"

Nothing is working not sure why
