And now, ladies and gentlemen, we return you to your regular programming. A MathEd bug!
Bug 2069: Movement out of sub/superscript works unexpectedly Description: When, at the leftmost end of the sub/superscript, you press left or, at any point in the sub/superscript, you press up/down (sub/super), the cursor is moved in front (left) of the object on which the sub/superscript is being added, as opposed to the right-most end of the object, below/above the super/subscript. If anyone can think of a word which refers to subscripts and superscripts collectively, that bug report would be much more readable. :P Cheers, Dan
