The Insert Symbol dialog provides a way to select and insert extended (symbol) characters into a Help topic.
Symbol: Displays a list of symbols that you can insert in your topics.
Insert: Copies the selected character into the topic (at the insertion point).
Close: Closes the dialog.
Note: These characters come from the standard HTML character set. To insert symbols from other character sets, insert them as images. For details, go to Adding images to topics.
