[edit] Basic usage
A RichTextBox can be added to a windows form by dragging its icon from the Toolbox. (TODO: Add image depicting this)
The text in the control, like the TextBox control can be found in the property RichTextBox.Text
[edit] Selection
The RichTextBox's selected text is stored in the RichTextBox.SelectedText property. To query the selection length, the RichTextBox.SelectionLength property can be used, and to find the start position of the selection, the RichTextBox.SelectionStart property is used.
