You can specify an id for a heading:

[h1:heading_id A heading to link to]

To link to it, you'll need to include the enclosing section's id:

[link document_id.section_id.heading_id The link text]

Although you can preceed a heading by an anchor if you wish to use a location independent link.

If a heading doesn't have an id, one will be automatically generated with a normalized name with name="document_id.section_id.normalized_header_text" (i.e. valid characters are a-z, A-Z, 0-9 and _. All non-valid characters are converted to underscore and all upper-case are converted to lower-case. For example: Heading 1 in section Section 2 will be normalized to section_2.heading_1). You can use:

[link document_id.section_id.normalized_header_text The link text]

to link to them. See Anchor links and Section for more info.

	Note
	Specifying heading ids is a quickbook 1.6 feature, earlier versions don't support them.
