This problem has bother me for a long time, it’s when we’ve created tons of the elements/widgets, then created a “New Interaction”, it’s getting harder and harder to select that exactly target even Axure provided “Filter” and “Search”, then I realize why Axure provide a fast way to select the elements/widgets, the picture shows how it works.
Way 1: Just like Adobe Effects
Way 2: Like Chrome “Developer tools > Select an element” (Ctrl+Shift+C)
