Edit Commands Disabled

I’m trying to copy a section of a track (MP3) but, the Copy command and Copy button are disabled. I locate the section I want to copy and highlight it to select it but when I open the Edit menu, Copy is grayed-out. Is there some secret to using the Edit commands that I’m missing? I’m running Audacity 2.0.6 on Windows 7. Thanks.

You are almost certainly in Pause mode rather than Stop mode. Press the Stop button and then try the editing.
