Suggestion, add keyboard shortcuts

[gem76]

Hello,

i like using shortcuts, so i added tabindex 1 and 2 to searchform and tagfilter, so i can quickly jump to them with TAB after loading the page.
It would be great to jump to the search results by using some shortcuts (e.g. ALT+12345).
Because of the dynamic creation of the hits i can't just add another tabindex.

Maybe you could give it a thought.
