Note 1: Unquoted text that is not a command is considered to be a variable. Variables are, by default, italicized.

Note 2: There are three custom fonts: serif (with serifs), sans (sans serif, meaning without serifs), and fixed (monospaced). To change the actual fonts used for custom fonts and the fonts used for variables (unquoted text), numbers and functions, use Format > Fonts.

Note 3: For all coloring, the color will apply only to the text immediately following the command until the next space is encountered. In order to have the color apply to more characters, place the text you want in color in curly brackets.

Characters – Greek

Warning: according to the OpenOffice documentation, these names for the greek letters are localised depending on your user interface language. So you can consult the symbol 'catalog' in the formula editor, in order to see what the names are on your system. Also note that around 2010, LibreOffice changed the greek letters to their non-italic, and we now need to use '%irho', '%itheta' etc to access the italicised Greek letters on most systems. This can be modified by changing the symbol catalog, but that's tedious.

Warning: the default symbol font on Ubuntu 12.04 and 14.04 is bad. You should modified the symbol font to Liberation Serif, if you want greek letters to appear properly.
