If you right click the control and go to find (in LV 8.0) and select say property nodes or references (assuming you have those) or terminals and it should pop up the Search Results window that shows you where all of those occur, in the current VI.
If you want to search for this in other VIs, click on the find button in the Search Results pop up window. You can then search for text or objest, select under Search Scope <All VIs in Application Instance> or a specified vi, and under include, check Hierarchy Window. If you check the vi.llb, you will get everything that is included in the National Instruments vis as well (and a lot of password protected files).
Now, you cant specify a property node for a specific control or indicator (that I know of), you can just select property node (under Select object) and it finds all the property nodes that you created in your vis.
