I check the news many times each day, and I like Safari's new RSS features. However, I find it cumbersome that to view all of my feeds, I need to click on the bookmark folder and then on the 'View all RSS Articles' link.
I wanted a quicker way to view all of my feeds. Safari assigns hotkeys to the links in the bookmark bar, but not to folders. My solution was to copy the URL of the 'all feeds' page (after activating it), and give it its own space in my bookmarks bar. The headlines still update automatically. Now, all of my headlines are just a command-3 away for me when I'm in Safari.
[robg adds: I hadn't though to bookmark the actual page's URL in order to use keyboard shortcuts. Instead, I used Bookmarks -> Show All Bookmarks menu, then enabled the Auto-Click item for the RSS folder. This at least got it down to a single mouse click. But I like the idea of a keyboard shortcut even better, so I've now switched over to this method.]
