Traveling?

[Splute]

Question on traveling.... I found this article on the Net regarding the 12 most confusing basketball rules http://www.betterbasketball.com/basketball-rules/

Can an offensive player travel when he is not in control of the ball?
If an offensive player attempts to catch a pass and bobbles or fumbles the ball, that player is not in control of the ball. There cannot be a traveling call when the offensive player doesn’t have the ball under control. Basketball rules states that once an offensive player has control of the ball and establishes a pivot foot, then a traveling violation should be called when appropriate.

If this is so, then how many steps do you allow a player to take while "not in possesion" or "under control"? Obviously you wouldnt let him fumble the ball down half the court. I know this sounds like a stupid question, but I like to remove all doubt from my mind on what is allowed by rule.
