You can quickly open the first nine links on the Bookmark Bars of Camino and Safari by hitting Command+1 through Command+9. Editor’s note: This is quite useful, especially if you use bookmarklets that do things, like send the current URL to Tweetie for sharing on Twitter or save the page to Evernote.
I knew about this keyboard shortcut, but it is a great suggestion to use it for faster access to bookmarklets. I just rearranged my Safari bookmarks bar this evening with this in mind.
