Firefox: go you keyboard shortcuts for research

When you visit a Web site, and you are looking for a specific word on the page, you can use the shortcut Ctrl + F. But you can do more simple.
Start by clicking the Tools menu, then Options. Open the Advanced section and in the General tab, Accessibility part, check the Start search when entering text. Confirm with OK.
Now to start the search, simply type directly the letters on your keyboard, and Firefox will display the result directly.
