Hi, sorry if I'm missing something basic here... In the Track View, if I want to zoom in and edit an area which is a lot smaller than the loop playback region -- that is, if I want to hear something which is longer than what I see --  I need to stop auto-scrolling on playback. 
 
I know can do this by going to the Clips Pane's Track view Options menu >>> Click Behavior >>> choose Left Click Locks Scroll. Then when I left click on a clip within the range I want to view, scrolling stops -- but only while I keep the left mouse button down. As soon as I release it, scrolling resumes. This is only so useful, because once I get zoomed in, I need the mouse for other editing tasks.
 
Is there another way to toggle autoscrolling on / off?

the scroll lock key

That was indeed something basic ...Glad I hedged my words!
 
Thanks! 

Yes Scroll Lock key is another way, but you shouldn't have to hold the click to keep the other scroll lock engaged (they operate independently); it should latch on a momentary click, and you should have to click the timeline or an empty area of the clips pane to disengage it. Are you clicking a clip to engage it, or somewhere else?

A request to the bakers who deal with documentation -- this could have been *a lot* easier to figure out.
 
I searched the online help for "auto scroll" and read through all nine hits. The only relevant only advice was to use the  Left Click Locks Scroll  option; there was no mention of the Scroll Lock key. So I searched the Hopkinton PDF manual for "auto scroll." The only occurrences were on page 448 :
 
"To enable/disable auto scroll lock: Click the Track view Options menu, point to Click Behavior and choose Left Click Locks Scroll on the submenu."
 
and something echoing this on page 1739. Again, no mention of the scroll lock button option.
 
Now, if I'd already known the answer, and searched the PDF for "scroll lock", you'd have to go to page 1325, which mentions it in a Staff View context, and then finally, if you want to know about non-Staff View, you have to go on to page p. 1539 of the manual:
 
"The SCROLL LOCK key toggles whether or not SONAR scrolls during playback."
 
Eureka ... well, we got there in the end...
 
But sorry, but page 1539 is just buried. While in retrospect, scroll lock is an obvious answer, well
 
a) ymmv; as the years go by, fewer and fewer apps I use make much important use of old IBM keys like ScrLock and PrintScr, so they're quite on my periphery; and
 
b) if it's so obvious, perhaps it should have been stated -- like many other "obvious" things -- somewhere higher up in the manual / help file.  I personally would suggest mentioning the Scroll Lock key method in the same places that you mention the Left Click Locks Scroll method. Keeps things organised by topic, from a user's point of view.
 
I know this sounds petty, but as someone who really tries to consult the online help, the manual (both of which are usually pretty great), google, videos etc before posting a query, I get really annoyed when something so basic is made so obscure. It leads to an unneccessary downtime and forays on the stop-start-headscratch-wtf-doh! cycle. If I'd had no internet access today, I might still be facing downtime, or postponing what I wanted to do until I could ask here. Shouldn't have to be this way -- the bundled documentation should do the trick.

Thanks for posting. 
 
I am left-clicking (and holding) the clip to engage it. Using the Select tool.   I'm seeing the following:
 
--Left click momentarily: scrolling doesn't lock
--Left click and hold, let the loop area play once or twice, then release mouse: scrolling stops when I click, then starts when I release the mouse button
--Left click and hold, let the loop area play more than twice, then release mouse: scrolling stops when I click, and stays stopped, even after the mouse is released
 
The third is what I want. If this is how it's supposed to work, that's kind of obscure. If it isn't how it's supposed to work, then maybe somewhere in the mysterious interplay between my SPLAT version, my project, and my hardware there is some problem.
 
But as ScrLock works fine, I 'll class it as low-to-no priority for me to debug, and get back to music making ... 
 
Thanks again.

Possibly this is a limitation/bug involving just the Select tool. Try it with the Smart tool.

Information about Scroll Lock button is hidden for purpose. It is a secret test. If you learn it, you pass the quest, you Sonar level become higher.

Thanks Brundelfly. Tried it. With the Smart Tool it engages as it should. But it doesn't disengage as it should, i.e. " click the timeline or an empty area of the clips pane to disengage it" doesn't work.
 
Whatever. ScrLk just works as it should. I'll mark this as solved. 

I usually use the keyboard option, myself, as it's not always convenient to find an empty area to click to resume scrolling. I recalled someone saying that clicking in the timeline worked also, but I just checked, and only right-click would do it. And that also opened the context menu for the timeline, which I then had to escape. 
 
Back to the keyboard method for me.
