The size feature should be explained in the fontspec manual, but the
macros used inside it in the example I sent are part of LaTeX kernel.

`texdoc expl` should do the trick.

Accent placement is controlled by the font, to change it (e.g. when
using a font that is not an OpenType math font) you might want to
"patch" the font on the fly, but that is even much lower level. Anyway,
the default is to center the accent on the glyph box, are you getting
something different?
