What is this button for ?
Multi-edit tool (velocity editor only). This tool allows you to perform transformations on a range of velocities. Click and hold the mouse button, then drag across a range of velocities to determine the range to be transformed. The specific transformations that can be performed are described below.

Thanks Marc. I click and hold the mouse button and drag but it does nothing
Got it. You have to hold a “long” time
I noticed that with th arrow button, you cannot select anything.
