Adobe has released Lightroom 4.2 with a number of fixes applied to the professional photo cataloging and editing application. The update includes a fix for stacked photos that were hidden in both the Grid view and Filmstrip, resolves a problem with publishing videos to Facebook, ensures that Lightroom photo can be edited as JPEGs in Photoshop Elements, and fixes an issue with carriage returns in either the Title or Caption field that invalidated a Flickr upload. The release also adds support for 22 new cameras (though offering just preliminary support for the Nikon D600) and 43 new lenses. ($149 new, free update, 407 MB, release notes)
Enter Dashboard, Expose, or Spaces Temporarily
Hold down F9, F10, F11, or F12 (or whatever you've set for the Expose and Spaces keyboard shortcuts) for a few seconds, and then release the key to enter and leave the appropriate mode without having to press the key again. This is particularly useful for Dashboard, in which you can check the contents of a widget and then return to your work with only a single key press.
