I tried using event.source.parent.getComponent in a client event script, but I get an error message that says ‘event’ is not defined.

Which event? And for those that do have `event`, you can’t expect an `event.source` to be there, as they don’t occur in any window context.

I’m using the keystroke client event. If F3 is pressed, for instance, it would set a component property.

You’ll have to use `system.gui.getWindow()` or `.findWindows()` to obtain the relevant window (handling the window-not-open case) and drilling down into its components via its `rootContainer`. Client events don’t happen in a window or a component. They happen in the application at a global level.

If you want F3 to mean different things in different windows, you’ll have to code that into the one script.
