How come TexPoint’s inline mode understands macros such as alpha but not frac, ar, or array or sqrt?
The inline mode supports a very limited set of macros (essentially the math symbols, subscript and superscript and some font changing macros; these are all listed in the accompanying TexPointDemo.ppt presentation). There are two main reasons for these limitations: (1) PowerPoint cannot position symbols arbitrarily but only one following another; and (2) TexPoint incorporates only a minuscule Tex interpreter so it could not handle complicated macros such as \bar. Note however that TexPoint does support user-defined macros with arguments. If you use the display mode you get the whole power of Latex but the result are images that do not flow with the text like the stuff produced with the inline mode does.
