See "Time-display units".
Change time-display units
- To cycle through Timecode Base, Frames, and Feet + Frames, Ctrl-click (Windows) or Command-click (Mac OS) the current-time display. The current-time display is in the upper-left corner of the Timeline panel and at the bottom of the Layer, Composition, and Footage panels.
- To change time display units, choose File > Project Settings, and choose from the options in the Display Style section.
Thanks for the reply. In the project settings I switched from auto to 30 fps and that changed the units from f to s which is what I was looking to do. I appreciate your help. Here's another silly question. I'm having trouble hearing audio files on my Mac Pro. It's probably something simple in my settings but I'm brand new to After Effects and I'm a little overwelmed by the program. Maybe I'll have a grip on it by the time I die. At the rate it's going it'll probably kill me first though. Thanks again for the help.

Everyone is new at some time.
I recommend starting here: "Getting started with After Effects"
