The special editor codes #region and #endregion are used to create collapsible regions in the text. For example, SimCam will always output these commands for the initial simulator special commands so that they can be easily hidden during a simulation.
If you click the little minus (-) sign in front of the #region command, the region will collapse and be hidden.
Clicking the plus (+) sign in front of the three dots will expand the region.
Also, you can hover the mouse cursor over the three dots to see a preview of the region without expanding it.
