The Visual LISP code formatter can be used to identify and add missing parentheses to the code in the text editor window.
Parentheses added by the code formatter might not be placed in the correct locations. However, it might be best walk through your code and determine which parentheses are missing and insert them in the correct location.
If the current cursor position is just before an open parenthesis, Visual LISP matches that parenthesis with its closing parenthesis. If the cursor position is in the middle of an expression, Visual LISP matches the current expression's open parenthesis with its closing parenthesis.
If the current cursor position is just after a close parenthesis, Visual LISP matches that parenthesis with its opening parenthesis. If the cursor position is in the middle of an expression, Visual LISP matches the current expression's close parenthesis with its open parenthesis.
With the cursor positioned right before an open parenthesis, double-clicking also selects all text up to the matching close parenthesis, but does not move the cursor.
