How do you know the audio level of a keyframes

Question

I'm varying the audio levels of clips on the timeline by creating keyframes using the pen tool. I create four points:
1) -inf = beginning of fade-in
2) -5dB = end of fade-in
3) -5db = beginning of fade-out
4) -inf = end of fade-out
But when I'm going back to adjust points, how do I know what level they're at already without having to drag them away from their home position and then back?
Scrolling over them with the mouse (and not clicking) just gives me a crosshair and no info.
I want to make sure that points 2&3 are at the same level, so I can just move the envelope region between them up and down to change the volume. Any quick way to do this to speed up my process?

Specifically to address this point: if you mouse over the audio levels' rubber band segment BETWEEN your points 2) and 3) until the cursor changes to an up/down adjustment arrow ⬍, and move it up/down, it will adjust BOTH the levels at 2) and 3), maintaining the relative difference between them (or, if points 2) and 3) start at the same level, this adjustment will keep them equal as you drag them both up/down together in one action.)
As usual, much easier to DO it, rather than describe it!
