Apple Logic Pro /LogicExpress Discussion

Hello There,

I am a new user not used to the intricacies of Logic Pro.  My main
tool for audio recording, 
editing, mixing, and mastering has been Pro Tools TDM for many years.
 I need a little bit of 
help on doing certain audio editing tasks, such as:

1.  Snapping the end of a region to the beginning of another region.
2.  Creating a sync point or marker on a region, then snapping the
start of another region to 
that sync point or marker.
3.  Creating a sync point or marker on a region, then snapping the
end of another region to 
that sync point or marker.
4. Creating two sync points on 2 separate regions, then snapping each
of the regions to each 
others sync point.

Any advice would be greatly appreciated.

Thanks, Albert.
