Copy	Ctrl+C
Paste	Ctrl+V
Cut	Ctrl+X
Delete	Delete
Undo	Ctrl+Z
Redo	Ctrl+Y
InsertLineBreak	Shift+Enter
InsertPageBreak	Ctrl+Enter
ToggleBold	Ctrl+B, Ctrl+Shift+B
ToggleItalic	Ctrl+I, Ctrl+Shift+I
ToggleSuperscript	Ctrl+'+'
ToggleSubscript	Ctrl+Shift+'+'
ToggleUnderline	Ctrl+U

MoveCaret with parameter MoveCaretDirections.NextWord	Ctrl+Right Arrow
MoveCaret with parameter MoveCaretDirections.Up	Upper Arrow

MoveCaret with parameter MoveCaretDirections.DocumentEnd	Ctrl+End
MoveCaret with parameter MoveCaretDirections.PageUp	PageUp
MoveCaret with parameter MoveCaretDirections.PageDown	PageDown
ShowFindReplaceDialog	Ctrl+F
ShowFontPropertiesDialog	Ctrl+D
ShowInsertHyperlinkDialog	Ctrl+K

Now, these key shortcuts can be overridden and customized to the liking of the user. This can be achieved by creating a custom RichTextEditorInputBehavior descendant:

C#
    
public class MyInputBehavior : Telerik.WinForms.RichTextEditor.RichTextEditorInputBehavior
{
    public MyInputBehavior(RadRichTextBox editor) : base(editor)
    {
    }
    protected override void PerformCopyOperation(System.Windows.Forms.KeyEventArgs e)
    {
        base.PerformCutOperation(e);
    }      
}
VB.NET
Public Class MyInputBehavior
    Inherits Telerik.WinForms.RichTextEditor.RichTextEditorInputBehavior
    Public Sub New(ByVal editor As RadRichTextBox)
        MyBase.New(editor)
    End Sub
    Protected Overrides Sub PerformCopyOperation(ByVal e As System.Windows.Forms.KeyEventArgs)
        MyBase.PerformCutOperation(e)
    End Sub
End Class

The default behavior can be changed like this:

C#
            
radRichTextEditor1.InputHandler = new MyInputBehavior(radRichTextEditor1.RichTextBoxElement);
VB.NET
radRichTextEditor1.InputHandler = New MyInputBehavior(radRichTextEditor1.RichTextBoxElement)

Another way to customize the control behavior is to use the PreviewEditorKeyDown event. For example, pressing RightAlt causes Control and Alt to be sent as arguments to the PreviewKeyDown event. Thus, RightAlt+E triggers a formatting command for paragraph alignment instead of inputting the ę character. In that case, you can handle the PreviewEditorKeyDown event in the following way:

C#
    
void RichTextBoxElement_PreviewEditorKeyDown(object sender, PreviewEditorKeyEventArgs e)
{
    if ((Keyboard.IsKeyDown(Key.LeftShift) || Keyboard.IsKeyDown(Key.RightShift)))
    {
        e.SuppressDefaultAction = true;
    }
}
VB.NET
Private Sub RichTextBoxElement_PreviewEditorKeyDown(ByVal sender As Object, ByVal e As PreviewEditorKeyEventArgs)
    If (Keyboard.IsKeyDown(Key.LeftShift) OrElse Keyboard.IsKeyDown(Key.RightShift)) Then
        e.SuppressDefaultAction = True
    End If
End Sub
