title: Annotating Adobe Reader PDFs with math symbols
body: <p>Many of the math textbooks and other literature I read is in PDF format, so I frequently find myself annotating these with the Adobe Reader comments tool. </p>
  
  <p>I did find a <a href="http://cjasn.asnjournals.org/site/misc/annotating.pdf">helpful guide</a> here, but sometimes I'd like the option of inserting math symbols, too. Has anyone found a reliable way to insert math symbols, TeX, or other arbitrary formatting into the annotations? </p>
  
  <p>So far, the best I've come up with is to enter the unicode prefixed by "0x" and hit alt+X after it. Maybe with the Adobe javascript SDK you could write a script to shortcut this.</p>
