Question

I’m working on my own text editor in silverlight. I made different functions to make text in a richtextbox bold, italic or underlined. I want the functions to be run also when the user presses the combinations ctrl-B, ctrl-U, ctrl-I.

What would be the best solution for this?

You can detect user input with the KeyDown event of a RichTextBox. Then you can simply check for the right combination of key and modifier in that event handler and call your functions there:

private void MyRTB_KeyDown(object sender, KeyEventArgs e)
    {
        if (Keyboard.Modifiers == ModifierKeys.Control)
        {
            if (e.Key == Key.B) 
            {
                MakeBold();
            }
            else if (e.Key == Key.I)
            {
                MakeItalic();
            }
            else if (e.Key == Key.U)
            {
                Underline();
            }
        }
    }
