Question about Akimbo

Is there some sort of Dvar, setting or command that makes it so I can shoot both akimbo weapons at the same time while only pressing one button?

I have a multi-touch touchpad that only lets me press one button at a time (one finger click, two finger right-click), and I can't use akimbo very effectively since I can only use one gun at a time.

Please help. This is so frustrating. All I want to be able to do is have the game play normally except when I take akimbo out, then use left-click to fire both weapons.

A USB mouse is not an option.

I got flamed pretty heavily at the AlterIWNet forums for this question; I'm hoping you guys can be nicer.

Thanks!

Your pretty much sol then. Using a touchpad for playing games is pretty lulz worthy, but if you want to do good, than some form of actual mouse is going to have to be an option.
