Use the IntelliSense property page to modify settings that affect the behavior of IntelliSense for Visual C#. You can access the IntelliSense property page by clicking Options on the Tools menu, then clicking C# in the Text Editor folder, and then clicking IntelliSense.
The dialog boxes and menu commands you see might differ from those described in Help depending on your active settings or edition. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see Customizing Development Settings in Visual Studio.
The IntelliSense property page contains the following properties:
When this option is selected, IntelliSense automatically displays the completion list when you begin typing. When this option is not selected, IntelliSense completion is still available from the IntelliSense menu or by pressing CTRL+SPACE.
Place keywords in completion lists
When this option is selected, IntelliSense adds C# keywords, for example, class (C# Reference), to the completion list.
Place code snippets in completion lists
When this option is selected, IntelliSense adds aliases for C# code snippets to the completion list. In the case where the code snippet alias is the same as a keyword, for example, class (C# Reference), the keyword is replaced by the shortcut. For more information, see Visual C# Code Snippets.
When this option is selected, IntelliSense pre-selects the members that you have recently selected in the pop-up List Members box for automatic object name completion, during your current session in the integrated development environment (IDE). The history of most recently used members is cleared between each session in the IDE. For more information, see IntelliSense for Most Recently Used Members.
