Could someone please enlighten me on this? There are two different editing environments in the notebook front end. The "text editor," is used for handling regular text (TextData), possibly with some style enrichments such as modifications in font family, color, weight, etc. This editor is normally used in heading and text style cells. It is also used for cells that use the InputForm format type. The other is the "math" editor. It is used to manipulate anything in the notebook that is represented as a two-dimensional typeset structures (BoxData). The math editor is used wherever the front end is configured to use the StandardForm or TraditionalForm format types. The front end switches between editing environments based on settings that normally reside in your notebook's style sheet. When you attempt to enter a subscript in a plain text cell, the front end handles this by creating an inline cell and switching from the text editor to the math editor. The appearance of the space occupied by the inline cell is set by a cell style in your style sheet known as InlineCellEditing. It is applied to the contents of the inline cell if your text cursor resides within the boundaries of the cell. By default, this color RGBColor[1, 0.749996, 0.8], which produces that pink background color. Inline cells do not immediately obey the formatting settings of the encapsulating cell. Instead, the settings are inherited from one of the FormatType style cells that is in your notebook's style sheet. Just what FormatType is applied depends on the setting of the option. You can query this value by evaluating this expression in the notebook you're using: "TextInline" /. (CommonDefaultFormatTypes /. Options[EvaluationNotebook, CommonDefaultFormatTypes]) In most situations, TraditionalForm will be returned. However, you may be using a notebook that uses StandardForm instead. That would account for the use of Courier in your subscripting. If you open the style sheet notebook in use with the Format -> Edit Style Sheet ... menu command and then expose the cell group that has the heading "FormatType Styles", you'll see where all the mischief comes into play. TraditionalForm typically does not have an explicit font setting, so it inherits the default for the notebook. FontFamily /. Options[EvaluationNotebook, FontFamily] On most systems, this will return "Times" or the system lookalike for this font. However, StandardForm _does_ have a default font choice in most style sheets -- Courier. If your notebook is using StandardForm as the FormatType for inline cells, you could probably do one of two things to fix your problem. The first is to simply change the value of DefaultInlineFormatType to TraditionalForm by using the menu command Cell -> Default Inline Format Type -> TraditionalForm A less desirable alternative is to need to modify the FontFamily option that appears in the prototype cell for StandardForm. The reason that this is discouraged is that it will affect other cell styles which use the StandardForm prototype, which includes Input and Output style cells. -- P.J.
