Alternatives to Audacity on Linux?

I’ve used Audacity for years and never really liked it. It does the job for quick edits, but I find the UI clumsy and frustrating. Exporting multiple clips from a file is an awkward workflow.

It feels very fiddly with all the precise mousing needed to define and change selections.

Just recently I was getting annoyed because I inserted some markers into an audio file, and you would think that clicking a marker would bring the playback cursor to that point - instead it puts you into editing the text of the marker. The varispeed playback is really poor also. You slide a very fiddly horizontal slider to control the speed.

Is there any alternative that’s more keyboard driven and more intelligent? I think Renoise is the only major GUI program I’ve enjoyed using in a long time.

(Yeah, I already use sox where applicable)
