Created attachment 124392 [details] screenshot of symbol that I could not decipher I cannot find a complete list of keywords in the format that allows me to write code based on the symbol required. A list of symbols that appears to fall short of a few symbols is available at http://rapidtables.com/math/symbols/Basic_Math_Symbols.htm#set and google Scholar and other academic sources might provide further symbols that are not clearly documented in a manner that I can readily use them. The file named scr02-symbol.jpg highlights one of them. Other similar packages include Microsoft Mathematics available for download at https://www.microsoft.com/en-us/download/details.aspx?id=15702.

Isn't this enough: https://help.libreoffice.org/Math/Formula_Reference_Tables
The StarMath markup is listed in the sighted Wiki. And the LibreOffice Guides provide additional documentation of using StarMath input to the formula editor and manipulating additional symbol glyphs. https://help.libreoffice.org/Math/Math_Examples https://wiki.documentfoundation.org/images/f/f8/GS5009-GettingStartedWithMath.pdf https://wiki.documentfoundation.org/images/2/26/MG44-MathGuide.pdf And, there is now support for import of MathML from clipboard Extensions provide support for LaTex. http://roland65.free.fr/texmaths/ http://extensions.libreoffice.org/extension-center/texmaths-1 So, this is really rather a RTM issue, closing Not A Bug.
