1073741847Key DownGenerated on a control that has keyboard focus. If a key press matches a keyboard shortcut in the VI menu, such as Ctrl-C or Ctrl-V, LabVIEW does not generate a Key Down event, regardless of whether the menu item is enabled. Key Down Event Caveats
  • (Windows) F3 generates a Key Down event only in the LabVIEW Run-Time Engine.
  • LabVIEW only generates events for the Cluster»All Elements source when the cluster has keyboard focus, not when an individual element inside the cluster has keyboard focus.
