Getting Audasity to edit audeo files a whole lot easier

Good evening, I’d like to know, is there a way to make editing audio files in Audasity a whole lot easier?
I am a blind user, using Jaws on a Windows 10 PC computer.
I record my files from other audeo sorses.
But the problem is, I have long running times at both the begening and the end of my files.
I really want to chop thos off the begenning and the end of my files, so that I could burn them to CD.
Thinks in advance!
