Clarification: Subscripts and Superscripts

Created by: jahewson

First of all, thanks for this fantastic resource! I'm seeking to clarify some of the details of superscripts and subscripts:

• Figure 20 uses LargeOpItalicCorrection but Figure 21 uses ItalicCorrection, while Figure 22 uses neither but the text says if largeop="true" then italic correction actually is used?
• SuperBottom is mentioned in the text describing msup but does not appear in Figure 21. Instead we have SuperBottomShift.
• SuperscriptBaselineDropMax is mentioned in the text describing msup but needs a blue background as it's a math constant. Same for the text describing msubsup.
• SubShift is mentioned in the text describing msup instead of SuperShift.
• In the text describing msubsup conditions 3. and 6. are identical. I assume condition 6. is supposed to be describing SubscriptBaselineDrop instead?
• Text describing msubsup refers to SuperBottomShift, should this be SuperBottom?
• I find it quite difficult to see the difference between the red and orange colors, can the contrast between them be increased?
• SubShift may be SuperscriptShiftUpCramped or SuperscriptShiftUp but TeX has a 3rd option,sub1 vs. sub2 for display vs. text style, I assume this is a limitation of OpenType Math, but is it worth commenting on?
