Properties - Define properties.
  
  Description

    This view allows you to edit and define properties on the current
    object.

    Property types

      'boolean' -- 1 or 0. 

      'date' -- A 'DateTime' value, for example '12/31/1999 15:42:52 PST'.
      
      'float' -- A decimal number, for example '12.4'. 

      'int' -- An integer number, for example, '12'. 

      'lines', 'ulines' -- A list of strings, one per line. 

      'long' -- A long integer, for example '12232322322323232323423'. 

      'string', 'ustring' -- A string of characters, for example 'This is a string'. 

      'text', 'utext' -- A multi-line string, for example a paragraph. 

      'tokens', 'utokens' -- A list of strings separated by white space, for example
      'one two three'. 

      'selection' -- A string selected by a pop-up menu. 

      'multiple selection' -- A list of strings selected by a selection list.

      Some of these textual properties come in two forms. The 'u'-prefixed
      form stores Unicode text. The form without the prefix stores a python
      plain string object, which is commonly assumed to contain latin-1
      text.
