+/**
+ * This interfaces provides access to extended editing-related functionality,
+ *  that is only available on s40-devices:<p>
+ * <b>Commands:</b><br>
+ * Applications can use {@link TextEditor#getTextEditorCommands()} and
+ * {@link TextEditor#launchTextEditorCommand(Command, int)} to present
+ * editing-commands in a customized way. When launching such a command,
+ * the application has to specify a command-mode. This is because some commands
+ * may require information regarding the key-state that has caused this command
+ * to be launched. For example, calling
+ * launchTextEditorCommand(cmd, COMMAND_MODE_KEYPRESS) for the "Clear"-command
+ * will cause to editor to keep deleting characters until the application calls
+ * launchTextEditorCommand(cmd, COMMAND_MODE_KEYRELEASE). Since not all commands
+ * require keystate-information, applications can use
+ * {@link com.nokia.mid.ui.S40TextEditor #isCommandKeyWanted(Command)}
+ * If no command-key is wanted, COMMAND_MODE_SELECTED should be passed
+ * when launching this command <p>
+ * <b>Indicator-icons</b><br>
+ * It is possible to access the indicator-icons that the platform would normally
+ * display as Images, using
+ * {@link com.nokia.mid.ui.S40TextEditor #getIndicatorIcons()} <p>
+ * <b>Visibility</b><br>
+ * Applications may be in the situation where they want an editor to be visible,
+ * but to not process keys or be animated, e.g. while a custom options-menu
+ * is displayed. In those cases, it is possible to call
+ * {@link com.nokia.mid.ui.S40TextEditor #setVisible(int)} <p>
+ * <b>Extra properties</b><br>
+ * Some properties that are not available in the com.nokia.mid.ui.TextEditor,
+ * like writing-direction, native emoticon support and positioning for native
+ * popup-windows.  <p>
+ * On s40-devices this interface is implemented by the object returned by
+ * {@link com.nokia.mid.ui.TextEditor#createTextEditor(String, int, int, int,
+ * int)} if the MIDlet is manufacturer- or operator-signed
