The Bookmark List allows you to create, delete, or edit bookmarks.
The Address field must contain a number in the range from 0 to 9,223,372,036,854,775,807
(7FFFFFFFFFFFFFFF hexadecimal). Space characters and commas are allowed and may be used to
improve readability of long numbers.
As in other dialogs, FlexHEX assumes the number is hexadecimal if it contains
hexadecimal digits A to F. Otherwise it is treated according to
the Dec/Hex selector.
Name is optional and may be empty. However if it is specified,
it must be unique for the current stream.
