Does Mathcad Prime 4.0 has the functionality similar to Ctrl+Shift+J.

 

After a long spell, I am back to using MathCAD. Please help.

No!

But see one my chemical calculation in Prime

Thanks for the reply. Since conversion to Prime products, I am too sluggish in Mathcad. I don't get to do what I need and decided to wait.

After a long spell of silence, I started last week. I came across with this chemistry-notation.

Chemistry notation is useful in my mechanical engineering calculations: for now, I will wait.

 

In your sample, I see your variables in square brackets; e.g. [Mg++].

Is it not a matrix variable? If so, how did you create it?  Please reply.

I copy variables with square brackets from one old sheet and edit it in one new sheet!

    First let me say that staying with Mathcad 15 is a very good idea anyway, as Prime still is far below MC15 when it comes to functionality, speed or ease of use.

    But you can create variable with "odd" characters like square brackets, if you first type the variable name in quotation marks and then delete the quotes.

    So the sequence "[abc]<del> should give you a valid variable name [abc] you then can subscript as  needed.

    This is similar to ctrl-shift-k in Mathcad 15.

      Thank, Werner! I always forget about this trick (first type the variable name in quotation marks and then delete the quotes) and just copy the chemical and others nonstandard variables from old documents. This one line variables for example: mol/L (molarity), g/mol (molar mass), mol/kg (molality), J/mol etc...

      Prime works a bit differently.

       

      To get a literal subscript in Prime it's "ctrl -", the control key and the minus sign.  This toggles, however. 

       

      To get the symbol for water  type "H, Ctrl-, 2, Ctrl-, O",

        Thank you very much Fred. I did not know it.
