/* How to add a new hotkey:
 *  add a new id in the enum hotkey_id_commnand 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);
 *      "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_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 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 ...)
