Can I use the remote control as a wireless mouse or to navigate through slideshow-style presentations from a computer?

• Yes. See Operating Your Computer With the Remote Control.
  
  Note:
  If you are using the remote control to operate your computer, you cannot use the USB port to project your computer's display. You must use the projector's Computer (Component Video) or HDMI (EX5200/EX7200 only) port instead to project your computer's display.
