When creating topic titles, follow these guidelines:
nYou can define only one title footnote per topic, and it must be at the beginning of the topic. You cannot place title footnotes at spot references.
nSince you only need topic titles to identify topics that users can jump to or that can be displayed in Help dialog boxes, you might consider not assigning topic titles to topics that are displayed only in pop-up windows.
nEnter the title string exactly as it appears in the title heading of the topic text because it is the string Windows Help displays in dialog boxes and windows for the user. In the previous example, the topic title “Saving Files” exactly matches the bold heading “Saving Files” in the topic text.
nTitles can have as many as 127 standard characters, including accented characters. Any embedded spaces in the title count as characters. Windows Help truncates titles longer than 127 characters.
nWindows Help follows these rules when sorting titles alphabetically for the Search facility:
nShort titles come before long titles.
nPunctuation characters come before numeric characters.
nNumeric characters come before alphabetic characters.
