At the top of my lecture notes I define the following environments:

%Student copy

%My copy (uncomment out "%" below)    

Throughout my lecture notes I use the Notes environment to comment out bits of text, equations, lists, and parts of tables. Sometimes {\Notes ...} will encompass a line, other times half a page.

However, I know this really isn't the best way of doing things as {\LARGE ..} doesn't play nicely with equations. But I'm not really sure what to do instead. Any suggestions?


I only need the sections to appear white, i.e. when I print them off. Students fill in the gaps during lectures. I noticed that when I used my solution to blank off a couple of equations at a time, the colour setting goes odd. By odd I mean that sections are incorrectly coloured.

    Do you mean "comment out" as in prevent LaTeX from typesetting it (as if there were a comment character before each line), or as in preventing your students from seeing it? If the latter, then the comment package is not going to do what you want [although I could be wrong; Martin's answer below seems to do that]. I suspect it's the former. What's wrong with what you're doing now? Are you saying that equations aren't set in the LARGE font? – Matthew Leingang Oct 11 '10 at 11:20
  • The comment package is indeed not doing what you want since it won't leave gaps for the students to fill in stuff. – Hendrik Vogt Oct 16 '10 at 7:10
  • @Hendrik-vogt: To leave gaps, all I do is change the text colour from red to white. I just need something simple. – csgillespie Oct 18 '10 at 12:24

You might consider using the comment package for including/excluding environments. If you just change the text color the text can still be copy/pasted which might not be what you want.

  • Can the 'comment' package increase text size within the the notes region? – csgillespie Oct 10 '10 at 17:49
  • I edited the example to change both size and color of the comment. – Martin Heller Oct 10 '10 at 20:06
