You can display the Storyboard in regular or large Storyboard view. In regular Storyboard view, it appears below the image window. In large Storyboard view, it appears to the left of the browser, where the Library is usually displayed. Large Storyboard view displays more shots at once in the Storyboard.
You can do all operations, such as selecting or deleting shots, from either Storyboard view. You can display the large Storyboard view from all menus except the Editing menus, in which case, the Library always appears to the left of the browser.
To toggle between regular and large Storyboard view, press Q.
In Large Storyboard view, you can now define the size of thumbnails using the Alt+Q keyboard shortcut. This cycles between normal and double sized thumbnails.
If you have a DVI monitor connected to your system, you can use the full width of the DVI monitor to display the Large Storyboard view, using the Ctrl+Q keyboard shortcut.
