Yea that is true. That's when I would normally open the Chrome console, set a break point, and click through the local variable to see what might work for me, then try it out in the console until I get what I want, then paste it into sublime.

Sublime's auto completion just helps me a lot when I have to repeat things or if I have to change lots of text in different places all at once (tip: hold down command when clicking when you have your cursor somewhere else on the page)
