I was working on a project and accidentally hit the "z" I guess because the zoom tool came up and then every time I started clicking somewhere it would zoom instead of change the timeline start.  but when I figured out that the zoom tool was activated by the "z", I tried pressing it again to turn it off and it wouldn't turn off.
 
I had to exit sonar and restart for it to turn off.  was there something I didn't do right?  did I lock it on somehow?

Hi Beagle that catches a few out at first. It's a tool exactly the same as all the others just missing an icon on the tool bar. To exit it you need to change to a different tool. Press F5 to get back to the Smart Tool for example.

HTH

Ah!  thanks Karl!
