***UPDATE***
It was determined that this is a behavior update and NOT a bug. However, i'm keeping the Report link in case some users wanted to up-vote for a feature.
It looks like this is a bug. I was able to recreate it.
However, if you right click on the timeline's work area and select "Show audio time units", the behavior seems to be corrected.
I have filed a bug report, please upvote: "go to select clip end" bug: Goes one frame before clip's end – Adobe video & audio apps
Kevin-Monahan Can you please help us out with that?
I agree with Meg, I have never used this shortcut before, and it is better to use "Go to Next Edit Point" Instead.
