So I was messing around with the audacity program for Windows 7,then I accidently pressed something that I can’t undo,I tried to work while it was like that but it was too stressful.
In Windows, Control-F will “zoom” so the work fits left to right (FULL). There’s lots of other zooms and you might want to bone up on them because that’s the best way to select a small portion of audio for editing.
I settled on three main Zoom tools. Drag-select some portion of the show and Zoom into it with Control-E (SELECTION). If I went in too far, I can zoom out a little bit with Control-3 (you just have to memorize that one). As in your case, Zoom out Full with Control-F.
