I have to go through the binding list and unbind all those extra action bar binds blizz puts in by default. Now that those lists are kept server side (for blizz bindings) I'll to repeat this on every character since I can't duplicate the bindings file anymore. What a pain in the a$$. I do keep a few bindings in place: B to open all bags, mouse zooms, most of the move commands etc. But I remove most of those bindings.

Save yourself some trouble later and just unbind all that crap blizz put in. You know you won't need those extra action bar binds. Most of us use a bar mod anyway and those binds won't be applicable. Just keep the things you will really need.
