Hello, My usage of LabVIEW is fairly intermittent, so when I return to a large project it can take some time to re-orient myself with how my VIs interact with each other. I encountered an instance where I opened a subVI and was trying to figure out where the controls/indicators for the input/output terminals were. First I tried double-clicking one of the terminals in the top-right grid, and when that didn't appear to bring me to the appropriate indicator, I right-clicked on it and saw no option to bring me to the indicator of that specific node. Then I remembered that if I just click on a terminal grid node, it will highlight the indicator or control on the front panel. This is useful, except for when the front panel indicator has been hidden... which, in my case, it had. I could see that it was highlighting something, but there was no way to find out what it was since it only showed an outline. Unfortunately, that meant that the only way for me to reliably find out what the node references was to either look at the terminal labels on the subVI in the main VI (why can't these labels show up when hovering over the terminal grid on the VI itself? I just realized that I hadn't tried ctrl+H to see if these labels show up when hovering over the grid... they do) and ctrl+F to find the one I'm interested, or go through the block diagram and find any indicators of the same data type then showing them on the front panel and clicking the terminal node to see if it highlights the one I just unhid. My question, I guess, is if there happens to be a better way to go about this process in the future? It's not too bad for my current project since I've written each VI in it and think it's relatively clean so far, if it does take me a bit to get back into the groove of things and remember where things are after a time away from the project. However, I will be inheriting some rather messy, massive code from a coworker in a few years once he retires, and am worried it may be a headache to find how some of his subVIs are wired. So, I think I have a couple... ideas that I hope exist, but am afraid will be merely suggestions for features of limited usefulness. First, is there a setting/command to temporarily unhide every front panel control or indicator? Just something that you can turn on, find what you're looking for, then turn off to resume the original visibility settings of each node. Second, is there some way to take a control/indicator and find if it has an input/output terminal (without deleting it and seeing if one disappears from the grid...)? I'd be kind of surprised if this didn't exist since only one can connect to one other (right?), so the two-way link should be discoverable, I would think. Finally, I think it would be helpful if double-clicking a terminal grid node did... something. I wouldn't mind if it brought you to the node in the block diagram, but if it just had the same functionality of double-clicking the block diagram node (bringing you to the front panel control/indicator, and showing a faded version if it's normally hidden), that would be okay too. It should be noted that I'm using LabVIEW 2017, so perhaps that is affecting my ability to interact with the terminal grid as I would hope to. Also, my apologies if this type of question has been answered in the past... I tried searching but didn't come up with anything that fit my current conundrum. Anyway, thank you for reading through my minor gripe with this particular facet of LabVIEW - hopefully it will help me learn something new!

Another option would be to use VI scripting to just highlight the object on the front panel AND block diagram. This will let you find the terminal on the block diagram. Then if it is hidden on the front panel you can just right click on the block diagram terminal and make it visible.

Drop this VI in "C:\Program Files (x86)\National Instruments\LabVIEW XX\resource\dialog\QuickDrop\plugins" and you can unhide all controls with e.g. (ctrl+space) CTRL+U.
