How should "rich text" (format? RTF?) be stylized?

Question

The new Stacks editor introduces support for Rich Text Format (RTF) and although there are just 115 posts on MSE containing "rich text" (at the time of this writing) that number is likely to increase.

I tried researching how to properly stylize the name since the above sample of MSE posts already contains Rich Text, rich text, RichText, rich-text, etc... It also doesn't help consistency that Microsoft itself has documentation with varying stylings like rich-text, Rich Text and rich text, but also Richtext and RichText...

Can the community give some guidance on how to copy-edit the tech name?

Answer 1

Rich text, on its own, is just another way of saying formatted text, whereas Rich Text Format (RTF) is specifically a type of file format. They are two different things, AFAIK. All the examples from MSE refer to "rich text" as formatted text and not the file format.

Rich text:

In computing, formatted text, styled text, or rich text, as opposed to plain text, is digital text which has styling information beyond the minimum of semantic elements: colours, styles (boldface, italic), sizes, and special features in HTML (such as hyperlinks).

(Wikipedia)

You can store rich, formatted text in an Access database [...]

(Microsoft)

Rich Text Format (RTF):

The Rich Text Format (often abbreviated RTF) is a proprietary document file format with published specification developed by Microsoft Corporation from 1987 until 2008 for cross-platform document interchange with Microsoft products.

So "rich text" needn't be capitalized and should not be written as a single word (i.e., "richtext").
