When creating topic titles, keep the following guidelines in mind:
Titles can include up to 127 standard characters, including accented characters. Any space embedded in the title is counted as a character. Viewer truncates titles longer than 127 characters. Viewer displays titles in a list box when the Index or Search facilities are used.
When Viewer sorts titles alphabetically for the Index facility:
Uppercase letters come before lowercase letters.
Short titles (with fewer characters) come before longer titles (containing characters). For example, “Kentucky: Economy” comes before “Kentucky: Nickname” because it has one fewer character.
Punctuation characters come before numeric characters.
Numeric characters come before alphabetic characters.
Because the topic title acts as the main reference that the user sees for the topic, you generally want it to match the text of any heading you've formatted in the text. For example, in the previous example, the topic title “Kentucky: Economy” matches the bold heading “Economy” in the topic text.
