/* How to add a new hotkey:
 * add a new id in the enum hotkey_id_command like MY_NEW_ID_FUNCTION (see
 * hotkeys.h).
 * add a new Ki_HotkeyInfo entry like:
 *  static Ki_HotkeyInfo HkMyNewEntry(wxT("Command Label"), MY_NEW_ID_FUNCTION,
 *                                    default key value);
 * wxT("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 overridden
 * by the user hotkey list file
 * add the HkMyNewEntry pointer in the s_Schematic_Hotkey_List list or the
 * s_LibEdit_Hotkey_List list or s_Common_Hotkey_List if the same command is
 * added both in eeschema and libedit)
 * Add the new code in the switch in OnHotKey() function.
 * when the variable itemInEdit is true, an item is currently edited.
 * This can be useful 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 ...)
 *
 *  Key modifier are: GR_KB_CTRL GR_KB_ALT
