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

• Yes. See Connecting to a Computer for USB Mouse Control and Using the Remote Control as a Wireless Mouse for details.
  
  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 or HDMI (PowerLite 1760W/1770W/1775W only) port instead to project your computer's display.
