Title:  Level values

Level:  2 - slide

Seq:    7

Class:  slide

Body:

+ `1`  — Used for Title slide
+ `2` — Used for presentation materials

Note that, with the right Collection setting, the level value also determines the heading level that will be used.

However the heading level associated with the first `slide` note will be used for all slides, no matter their level values.
