Equation Wrapping
As per the original Post.
I believe I have the premium version of Mathcad PTC Prime 9 - but "ctrl" + "enter" never worked for me either. Actually, as far as I know, I have Professional version of Mathcad PTC Prime. M > About > just says I have Verison Prime 9.0.0.0. I pay something like $600 a year for the license.
Anyway "ctrl" + "enter" doesn't work for me for whatever reason.
