Editing Rich Text Format (section)

== Code syntax ==
It is programmed using groups, a backslash, a control word and a delimiter.  Groups are contained within curly braces ({}) and indicate which attributes should be applied to certain text.

The backslash (\) introduces a control word, which is a specifically programmed command for RTF.  Control words can have certain states in which they are active. These states are represented by numbers.  For example,

; {{code|\b0}}   :   indicates that the Bold text is off
; {{code|\b1}}   :   indicates that the Bold text is on
; {{code|\i0}}   :   indicates that the Italic text is off
; {{code|\i1}}   :   indicates that the Italic text is on
; {{code|\ul0}}   :   indicates that the Underline text is off
; {{code|\ul1}}   :   indicates that the Underline text is on
; {{code|\sub0}}   :   indicates that the Subscript text is off
; {{code|\sub1}}   :   indicates that the Subscript text is on
; {{code|\superscript0}}   :   indicates that the Superscript text is off
; {{code|\superscript1}}   :   indicates that the Superscript text is on

A delimiter is one of three things:

# A space
# A digit or hyphen (e.g. -23, 23, 275)
# A character other than a digit or letter (e.g. \, /, }) <ref>{{cite web|url=https://www.biblioscape.com/rtf15_spec.htm|title=Rich Text Format (RTF) Version 1.5 Specification|website=www.biblioscape.com}}</ref>

As an example, the following RTF code
<syntaxhighlight lang="tex">
 {\rtf1\ansi{\fonttbl\f0\fswiss Helvetica;}\f0\pard
 This is some {\b bold} text.\par
 }
</syntaxhighlight>
would be rendered as follows:

<blockquote style="font-family: Helvetica, Arial, sans-serif;">
This is some '''bold''' text.</blockquote>
