How to delete a function

[Former user]

By inadvertance, I've added an expression a=1+j that has been recognized as a fonction. I didn't find how to delete this expression. Could you help me to make Speedcrunch as clean as it was befor. Regards

In the View menu, you can open the list of Variables and User Functions, from where you can delete it. In your case, it should be a variable.
