Adds accesskey+f as shortcut for accessing Google search bar
< Add accesskey shortcut to Google search 피드백으로 돌아가기
Sorry, I'm not changing it because the intention was to have it match the MediaWiki shortcut. It's highly unfortunate that Google decided to use the Alt key as the access key.
However, it's really easy modify the script yourself to do what you want. Just change the f on the second-last line to a g or some other character. It's been three years and I haven't touched the script once, so I doubt it'll need updating over the years.
It still works in 2019
But you need Alt + F is occupied by Chrome, need to change to another key, like Alt + G
