/**
Auxiliary Function for T-CoGridStep-RunTestStepL.\n
Handles the following Key Events\n
1. Ctrl+ e - Exits the application\n
2. Ctrl+ t - Toggles the Title Lines\n
3. Ctrl+ r - Resets the grid to its default layout and sets the cursor position to the cell at the top of the window\n
4. Ctrl+ m - Sets the zoom factor \n
5. Ctrl+ p - Paginates the Grid \n
6. Ctrl+ i - Inserts columns \n
7. Ctrl+ d - Deletes columns \n
8. Ctrl+ c - Changes the grid colour settings\n
9. Shift+m - Sets the zoom factor\n
@return TKeyResponse indicating whether the key event has been handled or not.\n
