Switch Latching

[codalafin]

I want to use a physical switch to act how a boolean control does. Specifically I need the ability to use "latch when released", activating a case structure when the switch goes from True to False. I have no idea where to begin with doing this, but I've opened the digital input, set the channel it runs on, set it under a variable name, and gotten its true-false value. Where do I work from there?
Also, if the answer would be in LabView help, I'm sorry but for some stupid reason the help doesn't load on this computer. I waited 15 minutes for the "Boolean Controls" page to load hoping that might have an answer and it never did.
