Please help me with this looping task

Sorry I just can't figure this one out. So sonar has the cool feature of highlighting a section of a clip and by pressing Shift>space bar will solo and play the selected section (however, it plays and then looping is turned off). Here is what I would like to do:
 
highlight a section and have the now marker go to the beginning of that section (without having to click first and click again to highlight - if that makes sense)
have the highlighted section stay as loop points and loop until I stop it (but loop the whole song not just the clip)
 
Is there any quick way of doing this. thanks in advance -Jim
 

Shift g
This takes you to the beginning of a selection.

I also nap ctrl shift g to jump to end of selection.

Now you can click on any clip and go to the beginning or the end.

All you have to do is hi-lite along the timeline then click on the set loop...  

As both these kinds gents have mentioned above...
I just make a selection, Hit SHIFT+L then hit SHIFT+G.
This should create the loop then take you to the beginning of the loop.
 
You can also use the CTRL+ PAGE UP/PAGE DOWN shortcut to navigate one measure at a time.
This is not very commonly known (at least I don't hear too many talk about it much) but it is very helpful in navigating.
 
A few years back, I printed 10 pages of shortcuts out, now I know 90% of them by memory.
Shortcuts are mans best friend.
