Improving your keyword list in the search query report
Improving your keyword list is now even easier: instead of switching between keyword statistics and your keyword list, you can add and refine keywords right from the search query report.
Queries you add as keywords will be assigned to the group of the ad they triggered. When adding a query as a negative keyword, you can decide whether it will operate at the ad group or campaign level. You can likewise edit queries — e.g. add or remove operators or extra words — before adding them to your keyword list.
