I'm switching to Audition from Premiere for my Audio editing, Where are edit tools?

You'll find an explanation of JKL ripple trimming here: https://helpx.adobe.com/uk/premiere-pro/using/trimming-clips1.html

But almost in the same breath, I have to say that you won't find it in Audition, simply because it's incredibly 'granular'. It's intended to slip an edit a frame at a time, and in audio terms that's incredibly coarse; about 2000 samples, when Audition can edit single ones if you really want.

And that's the thing really - Audition is an audio editor, Premiere is a video editor. They have different facilities for different purposes. The sensible approach to editing audio for video is indeed to do the synchronous part of it in Premiere, and do the more subtle parts in Audition - but not the basic edit. So Trevor_Asq's recommendation is basically sound, although I'd disagree about Audition being sub-optimal unless that point is clarified - as I hope I've just done.

peterkellner1  wrote Thanks.  I watched the video and it did not talk about how to do the actual editing. I've played around some and it seems like when I'm in the multi-track view, I can edit but when I'm in single track, I can't. Is that true?

Not really - you can edit perfectly well in both, but only Multitrack is non-destructive. If you edit in waveform view and save the changes you make, your file will be altered, and that's not reversible. Sometimes there are good reasons for using Waveform view for editing, but most is done in Multitrack, which works fundamentally (as does Premiere) as a posh file player. The changes you make are stored in the Session file, and that's what controls the playback of individual clips. So your original file isn't touched at all. This means that you have to be a little careful in Multitrack, because if you double-click on a file it will open in Waveform view, and if you edit something in that's already been used elsewhere in your edit, then that will alter too. You do get warnings about this, though.
