  • Create a “Preferences” file Can save multiple preference files Apply preferences
  • Conversion to XHTML didn’t deal with images correctly Use IML for fixing OCR errors (problem with linebreaks) Export to Word Use Word as output and edit in word Add structure Add alt text Use MathType:Convert to convert the equations Problem with page numbers
  • Description of curve Can be parameterized Sounds, slider control
  • SWITCH TO JOHN’S Computer
  • SWITCH to NEIL’S computer
  • If time, SWITCH back to John for ChattyInfty
  • Math Accommodations
