Fast forward and rewind within a file

I have just played an LP into Audacity and it seems I will now have to play the whole thing through again to find where each track starts and ends. When I had a mac it had Garage Band and you could fast-forward or rewind to do that. Please put it in Audacity.
Thanks, Rick

To set the playback position anywhere on the waveform, click on the waveform.

If you can’t see all of the time line/waveform, zoom out so that you can (see here for help zooming
