Folks are now using Photoshop on the new "netbook" style laptops. These small portable computers are great for travelling, but you sacrifice screen size for convenience. Some readers have complained about the panels crowding out the work area. Well ... there's an easy solution to the "problem."
Press the Tab key to hide all of the panels, the Toolbox, and the Options Bar. Press Shift+Tab to just hide the side panels - leaving the Toolbox and the Options Bar.
