// Remark: the hotkey message info is used as keyword in hotkey config files and
// as comments in help windows, therefore translated only when displayed
// they are marked _HKI to be extracted by translation tools
// See hotkeys_basic.h for more info


/* 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(_HKI("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 the id event 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
 * Add the 'HkMyNewEntry' pointer in the  s_PlEditor_Hotkey_List list
 * Add the new code in the switch in OnHotKey() function.
 *
 *  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 ...)
