Inserting symbols
Symbols are used to indicate non-printable characters. You can insert a symbol by typing it or by using the Symbols dialog.
For example, to define a carriage return/line feed as an item restriction, from
the item restriction view area, right-click and select Insert Symbols from
the context menu. From the list of symbols, double-click CR and double-click
LF and select OK. The carriage return/line feed
symbols are displayed in angle brackets in the item restriction view area:
<CR><LF>
