Question:How to enter variales named x*

It's a simple question, but I could not find a hint in the help system.

In economics it is very common to name variables like Y*, π* etc. They are unique, e.g. Y* ≠ Y

How can I enter them? If I just do it, it is interpreted as a vector function.

From time to time, you even need variables that have an overline (or bar),  above the character in addition to the asterisk, or variables like Â*.

A similar problem are variables that are named y' (and shall not be differentiated).

 

BTW: This question section here is generally used for sophisticated mathematical problems. Is there a better place to post simple questins for beginners like me (or search for solutions)?

 

Thanks a lot !
