Question
The feature of "Ctrl+Shift+J" in MathCAD is missing in MathCAD Prime 3.0
[Ctrl] [Shift] J Type characters inside brackets as in chemistry notation in MathCAD 15 or the previous version
but I can't find the same feature in MathCAD Prime 3.0.
Please tell me where it is, or I recommend to adding it in the next version.
