Assembly: PresentationFramework (in PresentationFramework.dll)
The behavior for this command depends on the current selection. If the selection is non-empty, or if the selection is empty and the current caret position is at the beginning of a paragraph, this command is equivalent to IncreaseIndentation. If the caret is in a table cell (represented by the TableCell element), this command moves the caret to the next cell. If the caret is in the last cell of a table, this command causes a new row to be appended to the table, with the caret positioned in the first cell of the new row. Otherwise, a tab character is inserted in current position.
There is not necessarily an actual implementation that responds to this command on any given object; in many cases the implementation that responds to a command is the responsibility of the application writer.
The following example demonstrates how to invoke an editing command on an object that supports the command.
For this example, a RichTextBox serves as the command target. Note that RichTextBox implements the IInputElement interface (inherited from FrameworkElement), and that it includes native support for many editing commands.
The first argument for the Execute method is a command parameter. Most editing commands ignore the command parameter; in general, this parameter should be null for editing commands.
The second argument specifies the object to which the command will be routed. This object must implement the IInputElement interface, and should include a handler for the specified command. Generally, a command is ignored when invoked on an object that does not handle the command.
