LabVIEW 2015 adds the ability to write VIs to modify the shortcut menus of LabVIEW's editor environment. You can add, rearrange or replace shortcut menu items for the edit-time front panel and block diagram or for the block diagram at run-time. These plug-ins do not affect the panels of running VIs – they do not become part of applications that you build with LabVIEW. If you want to modify the run-time panel menus, use the menu editing nodes that have been available with LabVIEW for many versions.
Open and run this VI: <LabVIEW>\resource\plugins\PopupMenus\Create Shortcut Menu Plug-In From Template.vi
