I'm trying to type the following:
by using the ''underscript'' ctrl-+ feature of 2-D expression input.
It works fine in a regular input cell. But I need it as part of an ''inline expression'' in a text cell. And there I can only get a ''subscript'' instead of an ''underscript''.
But wait! It gets even stranger! This seems to only be a problem for the word ''lim''. Any other text can get an underscript.
So I guess I'll use the word ''limit'' even though it doesn't look very official.
Any insights appreciated.
