## Region Operations

A region has several areas in its on-screen representation:

- the waveform (the majority of the region's display area, normally)

- the trim bar (the colored bar below the waveform)

- the name (in the trim bar, text)

- the fade handles (small squares that default to the upper left + right corners)

- the fade shape (filled or empty curves representing fade in + fade out)

- the gain envelope (hidden by default)

Mouse operations on each area will do different things.
