2014-09-29 07:10:15 +0200 commented question Why does LibreOffice produce such bloated .odt files?

I don't have enough new info to merit an "answer", so I'll post this observation as a comment. I had a .docx file that I created in Word, brought home, and opened in LibreOffice. I ended up with a 4.5mB file, and LibreOffice was crashing/recovering frequently when I would go into the Formula Editor (doing math homework). When I opened a new Writer document and copy-pasted the contents from the Word document, the resulting file was 500kB.

I did some poking around, starting with this answer. The problem is that "oper" only accepts a character as its argument, so I needed to define a character for Union and (more graphically unique) one for Intersection. This other link on the site ( http://ask.libreoffice.org/en/questio... ) gave me the missing tidbit. So here's how it worked:

  1. Open the equation editor
  2. Select Tools/Catalog
  3. Select Symbol set "Special"
  4. Click one of the glyphs (it doesn't matter which)
  5. Hit Edit (don't worry, you won't change the glyph you picked... probably)
  6. Find the appropriate glyph in the symbol set (union and intersection were on the 6th row for me)
  7. Click the glyph
  8. Change the text in "Symbol" to your text (such as "union")
  9. Note that it's telling you that you'll change the definition of your existing symbol. It's lying.
  10. Hit "Add" (not Modify!)
  11. You'll see the new symbol added to the symbol set list.
  12. Close, and you can use your new symbol like a greek letter:

    oper %union from {n=1} to 10 A_n
    oper %intersection from {n=1} to 10 A_n
    

Hope that helps. This topic plus the linked one really saved my bacon, so I hope this gives something back.
