Edit | Evaluate Selection
This command is equivalent to pressing CTRL+SHIFT+V, clicking Evaluate selection on the Source window's shortcut menu, or using the ?? (Evaluate C++ Expression) command together with the selected text as its argument.
If the selected text includes more than one line, a syntax error results. If no text is selected in a Source window, you cannot use this command.
For more information about other features of Source windows, see Source Window.
