# Headings and folds

Six levels. A heading's gutter folds everything down to the next heading of the same or a higher level.

## Level two

Folding this one hides the level-three heading below it and its text.

### Level three

The fold is an overlay, never part of the document. Fold this page, export it, and the markdown comes out whole.

## A second level two

Folding the first level two leaves this one alone — the range stops at the next heading of the same level.

### Three headings is the threshold

At three or more headings a document grows the dash rail down its edge. This section alone has six, so the rail is there.
