i dont know, if it a feature, but when you zoom in the sample in the sample editor and you press play, you hear only what you see ?
If you cutting precise, you must zoom in, but you wont to hear the whole context, you can’t imagine, if it’s correct on this short peace. You must zoom out again.
yes, i like the idea of both options as well. as for keys, how about ENTER for ply from position/ play visible and SHIFT+ENTER for play whole sample, or something along those lines.
