I am using Delphi 2007 and the helpfile is not in sync with the GUI.

I am using Delphi 2007 and the helpfile is not in sync with the GUI.
From the help file when I press help button in this dialog:
  
"Code completion  Displays a list of properties, methods and events when you enter a class name followed by a period in the Code Editor. You can then select an item and press ENTER to add it to your code. 
If this option is not checked, you can still invoke code completion by pressing CTRL+SPACE. The default value is On (checked).   

Error Insight  Underlines invalid code and HTML in red. Positioning the cursor over invalid text displays a tooltip window containing the probable cause of the error. The default value is On (checked).   

Code Template Completion  Automatically adds a code template when you type a token that starts a template and press TAB. The default value is On (checked).   

Auto Complete Templates  Invokes code template completion when you press SPACE after you begin an existing template. When this option is disabled, you must press TAB to invoke template completion after you type in the template name. The default value is On (checked).   

Template Hints  Enables template hints. Template hints appear when you add a template in the Code Editor and tab between the preset cursor positions in the template. The default value is Off (unchecked)." 

So it seems that more checkboxes was added in GUI and none care about updating the docs.

So what is the exact purpose of the rest ?

- Code parameters.
  Display parameters when you type a new call to a method ?

- Tooltip expression evaluatiuon
  Display method signature when hover with mouse over a method ?

- Tooltip Symbol Insight
  ???

- ToolTip Help Insight
  ???

- Code Completion Auto paranthesis
