Secret gems in Snow Leopard

Just got a few so far, but I’m sure Twitter will yield lots more over the coming days, so I’m preparing for a gigantic list ;)

• Exposé
  • Press space to make the thumbnail under the cursor full-sized (for quick previews). @fraserspeirs
  • Press command-1 to sort windows by name. @mikeysan
  • Press command-2 to group by application. @mikeysan
• Dock
  • Minimize windows to “the application icon” is a setting on Dock, which will store your minimized windows in Exposé instead of on the right side of the dock. Highly recommended! @joar_at_work
• Other UI
  • Show hidden files and folders in an Open/Save dialog by pressing command-shift-period @gruber
• For devs
  • -[NSArray enumerateObjectsAtIndexes:options:usingBlock:] with NSEnumerationConcurrent. @fraserspeirs
  • /System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc is an interactive Javascript commandline tool. Could be useful? @ccgus
