When you are typing a function, you can display a ToolTip containing the complete function prototype, including parameters. For overloaded functions, you can select which parameter list you wish to view. The Parameter Info ToolTip is also displayed for nested functions.

To display Parameter Info

  1. With your insertion point next to a member function, type an open parenthesis as you normally would to enclose the parameter list.

  5. If you dismiss the parameter list before completing the function and wish to view it again, press CTRL+SHIFT+SPACE, or right-click in the Text editor and choose Parameter Info from the shortcut menu.
