     20  Naming and other conventions:
     21  All data needed for configuration of shortcuts are collected in metadata
     22  objects wich are of type Metadata.
     23  The text in a menu item to the right of the \t character is called shortcut.
     24  Examples of shortcuts: Ctrl+N, PgUp, Shift+Ctrl+X
     25  The shortcut, if it exists, consists of an optional modifier and a shortcut
     26  key. So the format of a shortcut is: [modifier +] shortcut_key.
     27  The text in a menu item describing the action is called function.
     28  wxid is the ID associated with the menu item.
     29  cfgid is the ID used in the configuration file associated with a shortcut.
