Generally, when I'm working on a specific task that affects a handful of files, I'll have all of those files open in tabs. This provides a visual cue for each file (i.e. I know the "main" file is in tab position 1, the class that it calls is in tab #2, etc etc).
Furthermore, I can switch between tabs quickly with cmd + 1, cmd + 2, etc, or via cmd + option + left/right arrow. This can be quicker than fuzzy matching (which sublime text supports, btw), and it requires less mental overhead of remembering what the file is called when you want to switch to it.
