[Rich Content Editor] Subscripts in one click

[Robert_Bruner]

The html editor used to have two buttons, one to enter superscript mode and a second to enter subscript mode.   Now, there is one, which gives you a superscript unless you pick off the subscript option it offers.   This makes entry of subscripts slower and more tedious.   Please bring back the one-click way to enter subscripts.    In my linear algebra course, i rarely need superscripts, but I need subscripts all the time.
