Cut a Section of Audio

Why is it so confusing to simply cut a section of audio out of a larger audio track and save it separately?

The left mouse click-and-drag waveform “selection” on the overall waveform graphic does not show any time stamp signature when dragging the sub-selection.

Even when I enter the proper START and STOP timestamps of the overall audio track at the bottom of the appplication window, Audacity will “play” that sub-section, but I cannot “Trim” that same selection to save it separately.

What am I missing?

Thanks all…
