Change url on safari search
To show the full URL in what Safari calls the 'Smart Search Field', make sure the following is set in Preferences:

Go to Safari &gt; Preferences (⌘+,)
Select the Advanced tab
Check the box &quot;Smart Search Field: [✓] Show full website address&quot;

Now you can edit the full URL by hand.




EDIT:
Notice how the URL is now displayed with first before the title?  Just the opposite of the OP's screenshot.  Now typing the right arrow ► will go to the end of the URL not the title as the URL is first.  (The URL and the Title are now swapped)
