Changing controls?

[Peanut]

We all know this a terrible port, but wouldn't it be possible to change a few of the control in the files? I can live with just about all of the controls except the sneak attack which is almost impossoble to do with the default controls. You need to press M1 and M2 at the same time... 33% of the time you end up kicing the guy, 33% you end up punching him and 33% of the time you actually do a sneak attack. Anyone know how to do this? I had a look at the binds_pc file, but I couldn't really find anywhwre to change this specific action. Any ideas? :)

The game also tells you that you can press M1 & spacebar for the sneak attack that actually works.
