Search functionality inside javascript editor

I've got a bunch of javascript in the editor (because Knack currently lacks any built-in way to detect duplicate records and prevent them from being entered by the end user).

The browser's search bar function does not reliably find all the text inside the javascript editor.

So we need either an update to Google Chrome or a search function inside this editor.

Additionally, many javascript editors allow the user to expand/collapse functions and loops by showing a small (-) or (+) in the left margin of the editor. That would also help keep things orderly.
