Couple questions from new Pro Tools user

[Dual0568]

So please bare with me...

When zooming in close and tabbing forward to each cut, how can you go backwards without zooming out?

I thought I read somewhere Pro Tools LE had 36 internal busses, but when I open Pro Tools I only have 16

How far backwards?

Pro Tools 7 and above feature 32 internal busses. If you're using an earlier version, it's only 16. If you're using 7 or above, and you still only have 16, you need to open your I/O Setup and set teh busses to the default value.
