My missing brain...

I know the answer to this is simple but I cannot seem to recall how to edit an audio volume envelope.

I have a track of audio with the volume envelope on a lane below it. I can add nodes to the envelope in this lane but how to edit them for detail (like changing the value from -15.7 to -15) is completely escaping me.

Like I said, I know this is simple, I’ve done it before, but cannot find the right info. HELP!!

Figured it out. The values of the nodes are displayed at the top left of the track display screen. Duh. I knew it was something simple. It’s Friday and I’m done.
