Well, if you go to Help -> Shortcuts, and scroll down just a little, you can make your own shortcut key for "Edit/Clip/Split".
I use Alt+S, as I find that to be both logical and easy to use. But this is configurable free software, right? Use whatever key(s) that makes you happy!
With this, you can easily split while sound is playing. It simply splits wherever the playhead is at the moment.
Making this one shortcut can save you (at least it did for me) sooooo much time.
