How Do I Syntax Check an Expression while in Wide Mode? (Magic xpa 2.x)
When you have entered an expression while not in Wide mode, pressing the Tab key checks the expression. It will cause a bell to sound and an error message to be displayed on the status line, if the expression is in error. This is useful because you can check the expression before you do a complete syntax check on the program.
However, when you are in Wide mode, pressing Tab actually inserts a Tab character into the expression. So, when you are in Wide mode there is another key combination, Ctrl+Enter (Edit->Confirm Expression).
