MathML Preferences
Oxygen XML Author Eclipse plugin allows you to edit MathML equations and displays the results in a preview window. For a more advanced MathML editor, you can either install Wiris MathType (which is a commercial product that requires a separate license) or use an external MathML editor (e.g. the LibreOffice equation editor).
Using MathFlow for Editing and Rendering MathML Equations (Deprecated)
Important: 
      The MathFlow editor integration has been
        marked as deprecated and was replaced with a new MathType
          integration.
To configure the MathML editor or to enter your MathFlow license information, open the Preferences dialog box and go to .
You can configure the following options:
      - Equation minimum font size
- The minimum size of the font used for rendering mathematical symbols when editing in the Author mode.
- MathFlow installation directory
- The installation folder for the MathFlow components product (MathFlow SDK).
- MathFlow license file
- The license file for the MathFlow components product (MathFlow SDK).
- MathFlow preferred editor
- A MathML formula can be edited in one of three editors of MathFlow
              components product (MathFlow SDK).- Structure Editor (default selection) - Targets professional XML workflow users.
- Style Editor - Tailored to the needs of content authors.
- Simple Editor - Designed for applications where end-users can enter mathematical equations without prior training and only the meaning of the math matters.
 
- Save special characters
- Specifies how special characters are saved in the XML file.- As entity names - Saves the characters in
                    &name;format. It refers to a character by the name of the entity that has the desired character as its replacement text. For example, the Greek Omega character is saved asΩ.
- As character entities (default selection) - Saves the
                  characters in a hexadecimal value, using the &#xNNNformat. For example, the Greek Omega character is saved asΩ.
- As character values - Saves the characters as the actual
                  symbol. For example, the Greek Omega character is saved as
                    Ω.

Using an External Tool for Editing MathML Equations
- 
              You can use this option to specify an external MathML application for editing MathML equations. For example, the following commands could be used to edit MathML equations with a LibreOffice application (depending on the O.S.):- Windows - "C:\Program Files\LibreOffice\program\smath.exe" --nologo "${cf}"
- macOS -
          /Applications/LibreOffice.app/Contents/MacOS/soffice --math --nologo "${cf}"
- Linux - /usr/lib/libreoffice/program/smath --nologo "${cf}"
 
- Windows -
