This JavaScript captures and stores all the phrases that Google auto-populates into the drop-down as you type for the purpose of creating long tail keywords.

Paste into a snippet, navigate to the google search, run the snippet, type the origins of you keywords. When done you will find a list of all the long tail keywords in the local storage item named "gogl_ai_keywords". In the console fire fLong.report(); to view results. Cut and paste into Textpad and fire macro named "gogl long tail console table", sort and dedupe.
