Or, simply clicking the Marquee Zoom tool increases the magnification by one preset level, centering on the point where you clicked. To decrease the magnification by one preset level, Ctrl-click/Option-click the Marquee Zoom tool.
  • The Dynamic Zoom tool zooms in when you drag it up the page and zooms out when you drag down. If you use a mouse wheel, this tool zooms in when you roll forward and zooms out when you roll backward.

  • The Zoom Value option changes the page view according to a percentage you type in or select from a pop-up menu.

  • Fit Width adjusts the magnification so that the PDF fills the document pane horizontally.
  • Fit Height adjusts the magnification so that one page fills the document pane vertically.
