/// <summary>Performs an action encapsulated in IEditAction.</summary>
/// <remarks>
/// There is an implementation of IEditAction for every action that
/// the user can invoke using a shortcut key (arrow keys, Ctrl+X, etc.)
/// The editor control doesn't provide a public funciton to perform one
/// of these actions directly, so I wrote DoEditAction() based on the
/// code in TextArea.ExecuteDialogKey(). You can call ExecuteDialogKey
/// directly, but it is more fragile because it takes a Keys value (e.g.
/// Keys.Left) instead of the action to perform.
/// <para/>
/// Clipboard commands could also be done by calling methods in
/// editor.ActiveTextAreaControl.TextArea.ClipboardHandler.
