/* How to add a new hotkey:
 *  add a new id in the enum hotkey_id_commnand like MY_NEW_ID_FUNCTION.
 *  add a new EDA_HOTKEY entry like:
 *  static EDA_HOTKEY HkMyNewEntry(wxT("Command Label"), MY_NEW_ID_FUNCTION, default key value);
 *      "Command Label" is the name used in hotkey list display, and the identifier in the
 *      hotkey list file MY_NEW_ID_FUNCTION is an equivalent id function used in the switch
 *      in OnHotKey() function.   default key value is the default hotkey for this command.
 *      Can be overrided by the user hotkey list file add the HkMyNewEntry pointer in the
 *      s_board_edit_Hotkey_List list ( or/and the s_module_edit_Hotkey_List list)  Add the
 *      new code in the switch in OnHotKey() function.   when the variable PopupOn is true,
 *      an item is currently edited.  This can be usefull if the new function cannot be
 *      executed while an item is currently being edited
 *  ( For example, one cannot start a new wire when a component is moving.)
 *
 *  Note: If an hotkey is a special key, be sure the corresponding wxWidget keycode (WXK_XXXX)
 *  is handled in the hotkey_name_descr s_Hotkey_Name_List list (see hotkeys_basic.cpp)
 *  and see this list for some ascii keys (space ...)
