Multiple command mapping limitations ?

I believe I just saw a post or blog about this but cant find it for the life of me..

I went thru my first mapping excercise for the bmasher pro to make some customizations so it was a great education in mapping/modifiers, etc.

But the part I get a little tripped up on is:
- What order do multiple commands go into Traktor?
- Is there a limit to how many?
- Or a limit to which kinds of controls?

I find sometimes when I put too much on a button, it only does 75% of what I believe it should do and then I have to go searching for a workaround. Ill try to provide a specific example next time I hit one.
