The Daily UserScript: Google Webmaster Keyword Insight Links
This userscript will add Google Insights search links to the Google Webmaster Tools keywords page.
The Unpleasantry:
Copying and pasting keywords from Google Webmaster Tools over to Google Insights for Search.
The Alleviation:
Once you install the "Google Webmaster Keyword Insight Links" UserScript you will find little Google Insights icons to the right of each keyword displayed on the keyword page of Google Webmaster Tools which will link to Google Insights data on the keyword.
