Probably the best thing to do before you hit the delete key is to verify 
your selection. The space bar will play your selected audio, and then if 
you need to extend it to the left, you can use shift+left arrow, or use 
shift+right arrow to extend it to the right. If you need to shorten the 
selection from its right boundary, use shift+control+left arrow, and if 
you need to shorten it from its left boundary, control+shift+right arrow 
will do that. Always verify you have the right part of the file selected 
before you press the delete key. But never fear if you do make a 
mistake, as you have virtually unlimited undo capabilities.
