What's the inverse of
Ctrl+L in a browser?
Say, you are typing the address but suddenly change your mind. Or maybe you forgot something on the current page and want to go back to it. How to do it, without using the mouse to click on the web page?
Try F6. It toggles between the address bar and the page for most browsers. If you're using Opera though, try Ctrl-L and Escape. ;-)
EDIT: In Chrome, hit F6 to toggle between the address bar, the bookmark bar, and then the page. If you've got the bookmark bar showing, hit F6 once to go from the page to the address bar, and twice to return to your last textbox in focus.
Don't think there are any shortcuts to jump back to where you were, it is rather a case of use a shortcut to take you where you want to go. Again, however, I don't think there is any shortcut to take you to the page body, but for me on Iceweasel (Firefox) a TAB takes me to the search bar and another takes me to the page body. Chromium just needs one tab. I doubt many browsers will be any more two.
So a short answer would be TAB once for Chrome and twice for Firefox.
