QuickDraw GX correction -- I regrettably and erroneously wrote in TidBITS-244 that you cannot generate a PostScript file by printing to disk through the Print dialog box. Using the LaserWriter GX driver, you can print to a PostScript file, much as you could using previous LaserWriter drivers. Sorry for the confusion. [TJE]
Full Screen Quick Look in Snow Leopard
When viewing files in the Finder in Snow Leopard, instead of pressing just the Space bar to enter Quick Look, press Option-Space to display the selected document in full-screen Quick Look, expanding the preview and hiding everything else that would otherwise remain visible.
