I love it when I'm just wandering around and find something truly useful (OK, I wasn't wandering - I used SharePoint Blogsearch to find one thing and stumbled across another). Here's a post from Todd Bleeker regarding javascript links that toggle page modes in SPS and WSS. I already new about appending ?toolpaneview=2 to the URL but this is even easier - and he explains what all the options are. Very cool. I had no idea you could do this with IE favorites.
Also, here's a great post from Serge van den Oever on FrontPage and Data View Web Parts. Very thorough and a must read.
