{{highlight}} {{citation}} {{comment}}
You can see that, by default, highlight annotations are added as a single paragraph, with the highlighted text followed by the citation and any comment. Quotation marks are automatically added around the highlight.
If you prefer to have the highlight text in a blockquote, it's a simple change:
{{highlight}}
{{citation}} {{comment}}
==== Conditionals ====
Templates also support conditionals. Rather than combining the citation and comment in a single paragraph as in the previous example, you might want to create a separate paragraph for the comment, but only if a comment actually exists. You can test whether a variable is set with a simple ''if'':
{{highlight}}
{{citation}}
{{if comment}}{{comment}}
{{endif}}
Conditionals can also be used to test for specific values. Here, text highlighted in red becomes a header without quotation marks, text highlighted in blue becomes a blockquote, and all other highlights use a single paragraph:
{{if color == '#ff6666'}}
{{highlight quotes='false'}}
{{elseif color == '#2ea8e5'}}
{{if comment}}{{comment}}:
{{endif}}{{highlight}}
{{citation}}
{{else}}
{{highlight}} {{citation}} {{comment}}{{if tags}} #{{tags join=' #'}}{{endif}}
{{endif}}
==== Variables ====
Here are the available variables and their supported parameters:
* ''highlight''
* ''quotes''
* omitted: Include quotation marks around text unless the highlight is placed within a blockquote
* "true": Always include quotation marks
* "false": Never include quotation marks. The highlight must be placed within a blockquote to remain as an active annotation.
* ''citation''
* ''comment''
* ''color'' — yellow: '#ffd400', red: '#ff6666', green: '#5fb236', blue: '#2ea8e5', purple: '#a28ae5', magenta: '#e56eee', orange: '#f19837', gray: '#aaaaaa'
* ''tags''
* ''join'' — string to use to join tags
(Note that ''color'' is primarily for use in conditionals. Annotation colors can be [[pdf_reader#displaying_annotation_colors|toggled on and off]] from the note editor menu. An upcoming version will add a preference for controlling whether colors are shown by default.)
