In Safari 8, after doing a Google search from the navbar, the focus stays on the navbar instead of focusing on the content like any other webpage.
This prevents the use of Google or DuckDuckGo keyboard shortcuts to open the first result quickly, for instance. You need to click on the page content first, and then you can use the keyboard navigation.
Is there a solution to make it easier? Extension, shortcut, setting, anything?
You can make a Service in 10.6 or 10.7 using Automator that will open a selected URL in Chrome.
Here's how:
When Automator asks you to Choose a type for your document window, select Service 
Change the "Service receives selected" drop-down to "URLs" 
Code:
on run {input}
set theURL to input
tell application "Google Chrome"
if not (exists first window) then
make new window
set URL of last tab of first window to theURL
else
tell first window
set newTab to make new tab with properties {URL:theURL}
end tell
end if
activate
end tell
end run
This will open any selected URL in Safari or other application in Chrome, either in a new tab in the most recent window, or a new window if there is no open Chrome window. To access it, right-click and under the Services item at the bottom of the menu, you should see an item with the name you assigned.
One important caveat: OS X seems to be a bit picky/buggy about passing link to this sort of service. It works fine if you have text selected as a URL, but it only seems to work on some links. If I discover a better method, I'll update this post with it.
You may also need to restart Safari for the service to appear.
If the main idea is scripting Safari, I would try using Automator before trying AppleScript. I'd start by hitting the record button and then:
GET by saving the webpage sourceOr you could try AppleScript with something like this:
tell application "Safari"
tell window 1
set current tab to (make new tab with properties {URL:"http://www.example.com"})
end tell
end tell
You can add to the script form fills and submit buttons with javascript:
do JavaScript "document.getElementById('field').value = '" & myvalue & "'"
do JavaScript "document.forms[\"form\"].submit();"
I'd try this out within the JavaScript console within a web browser first to make sure you have the names of everything correct.

If I understand you correctly, try OptionTab then down-arrow to the result you want and press return. There will be a tiny arrow to left of the selected link.
