How to Set the Instruments Inspection Range
I have, by accident, successfully set an inspection range in Instruments — and later I can’t reproduce it. This time I’ve figured it out for good, and so I’m writing it down.
Record for a while. Click the pause button.
Find the clear downward-pointing triangle above the graph. Click and drag it to the start of the range you want. Type cmd-< to set the beginning.
Click and drag that same triangle to move it to the end of the range you want. Type cmd-> to set the end of the range.
