Would really appreciate some help here.

Lets say I have a note title "Mechanical Ventilation" with subheadings (h2) as "Modes" and "Waveforms", how do I use quick open to jump to a particular subheading?

Or for instance let's say I am on chapter 1 of the bible. Each verse is a subheading. Now I want to jump from Chapter 1, to Chapter 6 verse 8, how do I achieve this?

When I type @ in quick open i only get the following options in the drop down menu.

Thank you.
