I am playing around with RIO and IR remote commands and I noticed that I have used IR command 0 but the "Show References" is empty but the graphical references shows the actual links. Also the text is not in blue.
"Show References" is supposed to show where the item selected is referenced
You have assigned the Response "IR 1 to Output 1" to IR Code 0. However there are no references to IR Code Received Code 0 because in general IR Receive Codes do not have references, or other places that refer to IR Receive Codes
It is the Response "IR 1 to Output 1 " which is referenced by IR Code 0, not the other way round
The Graph References do show IR Code 0 but that is showing IT Code 0 referencing the IR Response, not something else referencing IR Code 0
Graph references is more useful as it shows links upstream and downstream to the selcted item
