Use trademarks

You can insert a trademark into your content from the symbol menu or the insert attribute menu.

A trademark is a type of intellectual property consisting of a recognizable sign, design, or expression which identifies products or services. There are three pre-defined types of trademarks you can insert:
Trademark
A symbol, word, or words legally registered or established by use as representing a company or product.
Service mark
Trademarks used to identify services are called service marks.
Register mark
Provides notice that the preceding word or symbol has been registered with a national trademark office.

You can insert all pre-defined trademarks using either the symbol character picker or by inserting a Trademark attribute.

The register mark and trademark are quickly accessible using the symbol character picker shown below. You can search More symbols... to add the service mark.

You can also insert a Trademark attribute, and then edit the Value field to select the type you want, as shown below.
