Doing a search on Google, here's a nice little tip to save you time;
Let's say that you've typed a query and pressed Enter, but the results aren't great. To quickly delete your query and type a new one -- Just press "Esc" and start typing the new query. Another option is to click on the small "x" icon from the search box.
If you want to add some new keywords to your query, there's no need to scroll to the top of the page and find the search box. Just type the words you want to add. Google is smart enough to insert a space since this key is used for scrolling.
This only works if Google Instant is enabled, just like the other Google search shortcuts and Google Instant shortcuts.
