When you are searching from Chrome's address bar, you can trigger Lucky search (instant redirect to the first search result) by typing your search keyword in a certain manner, for example:
- Ending it with a capital letter
- Ending it with any meaningless symbol (meaningless in terms of Google's search) like an exclamation mark or a dot.
- Ending it with a predefined symbol sequence, like !!!
- Searching in UPPERCASE
Why would you want to do a lucky search?
Please note that due to current extension limitations (it is not possible to catch what you have typed in omnibar) lucky search might be triggered after showing a regular google search page for a few moments. Also because there is no way to separate omnibar search from a context menu search, all trigger rules apply for any search made from Chrome (omnibar, page context menu, "paste and search" menu).
