I've always had issues navigating the Debugger's list of objects because when the list gets long, it takes longer and longer to scroll through the list. Watching variables isn't always the solution because 1.) newly-created variables don't show up, and/or 2.) the reason for searching the object is to find out its count, and/or 3.) there are just too many watch variables already.
I don't know why I didn't think of this before, but the solution is DevTools. Under the Elements tab, hit CTRL+F, and type in the object name. This searches the whole frame, though, so it's obviously helpful to name the objects in a way that is easily referenced.
