Using tag names and tag placeholders

A tag name can be included as part of an expression or can stand
alone as the entire expression.

To supply a tag name, do one of the following:

type a tag name

You can type a tag name that does not exist in the tag database.
When you click OK, a dialog box appears prompting you to create
the tag.

click the Tags button and select a tag from the Tags list

Enclose tag names that contain dashes or start with a number in
braces { } when you use them in an expression. This distinguishes the
characters in the tag name from the characters in the expression. Also
use braces when using wildcards (* or ?) to represent multiple tags in
an expression.

For detailed information about tags, see Chapter 4, Creating tags.

This

character

Does this

?

Matches any single character.

*

backslash (\) character.

Use this wildcard by itself to display all the tags in the
tag database.
