|OnAfterSnippetsKeyBindingChange||Called after there has been a change in the key binding for the Invoke Snippet From Shortcut command.|
|OnAfterSnippetsUpdate||Called whenever a folder that contains snippets has been updated and the snippets from that folder have been read in.|
|OnAutoComplete||Called when the AUTOCOMPLETE command is received.|
|OnChangeCaretLine||Called when the caret moves to another line.|
|OnChangeScrollInfo||Called when the scroll information for the specified scroll bar has changed.|

|QueryCommandStatus||Determines if the specified command is supported.|
|QueryParameterList||Called to obtain the parameter for the specified command.|
|ReformatDocument||Handles the FORMATDOCUMENT command to reformat the entire document.|
|ReformatSelection||Handles the FORMATSELECTION command to reformat a selection.|
|RegisterExpansionManagerEventHandlers||Registers event handlers IVsExpansionEvents.|

|ShowContextMenu(Int32, Guid, IOleCommandTarget)|
|ShowContextMenu(Int32, Guid, IOleCommandTarget, Int32, Int32)||Handles the SHOWCONTEXTMENU command to show a context menu.|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|TypeChar||Executes a TYPECHAR on the current command target chain.|
|UncommentSelection||Handles the UNCOMMENTBLOCK command to uncomment the current selection in the current view.|
In addition to the cursor, Enter, Backspace, and Delete key commands, this base class provides support for the following commands:
IntelliSense: select member from member list.
IntelliSense: show member list.
IntelliSense: complete word being typed.
IntelliSense: show parameter information.
IntelliSense: show information about an identifier.
Editing (advanced): go to definition.
Editing (advanced): go to declaration.
Editing (advanced): go to a reference.
Editing (advanced): comment a span of code.
Editing (Advanced): uncomment a span of code.
Editing (outlining): stop outlining.
Editing (outlining): toggle outlining.
Editing: show a context menu.
This class already implements all of the support for IntelliSense as well as various advanced editing features. However, if you want to support additional commands in your language service, then you must derive a class from this class and override the appropriate methods:
QueryCommandStatus (to indicate support for your commands)
QueryParameterList (if your commands require parameters)
HandlePreExec (if your commands require some set up)
HandlePostExec (if your commands require clean up after execution).
ExecCommand (to execute the command).
This class is instantiated in the CreateViewFilter method of the LanguageService class that is in turn called from the OnNewView method in the CodeWindowManager class when a view is attached to a source file.
